OPINION

BROWN, J.

Since 1996, the Legislature has directed that upon conviction of lewd and lascivious acts with a child, in violation of Penal Code section 288, a defendant shall be ordered "to submit to a blood . . . test for evidence of antibodies to the probable causative agent of acquired immune deficiency syndrome (AIDS)" "if the court finds that there is probable cause to believe that blood, semen, or any other bodily fluid capable of transmitting HIV [human immunodeficiency virus] has been transferred from the defendant to the victim: [¶] . . . [¶] For purposes of this paragraph, the court shall note its finding on the court docket and minute order if one is prepared." (Pen. Code, § 1202.1, subds. (a), (e)(6)(A), (B).) The question presented is whether a defendant may challenge such an order on appeal if he has failed to object to the absence of an express finding of probable cause or docket notation.

We conclude that appeal of an HIV testing order on this basis should be subject to the general rule requiring a timely objection. Accordingly, we affirm the judgment of the Court of Appeal.

FACTUAL AND PROCEDURAL BACKGROUND

Defendant Timothy Brian Stowell was charged with violating Penal Code sections 288, subdivision (a) (lewd and lascivious acts with a minor), and 289, subdivision (j) (sexual penetration of a minor with a foreign object). Because defendant does not challenge the sufficiency of the evidence in any regard, we recount the facts only briefly as distilled from the Court of Appeal opinion.

On July 25, 1998, Tracie H. and her four-year-old daughter, Taylor — the victim — spent the day with defendant and his girlfriend, LeaAnn Thompson. That evening, they returned to the motel where defendant and Thompson lived (Thompson was the resident manager). Tracie decided she and Taylor would spend the night. They went to sleep in the bedroom while defendant and Thompson remained in the living room. About 2:30 a.m., Tracie was awakened by Taylor's "rustling" in the bed and told her to settle down. Tracie then heard a male voice say "tight little pussy" and Taylor say "Don't, Tim. Quit it." She asked, "Taylor, what is he doing to you?" Taylor responded, "He's got his finger in my pee-pee." Tracie immediately took Taylor from the bed and left the motel.

When interviewed by the police, defendant first stated that he had no recollection of getting into the bed with Taylor or of touching her. In a second interview, he admitted inserting his finger into Taylor's vagina.

The jury found defendant guilty on both counts. The court determined he was ineligible for probation and sentenced him to six years in prison. It also ordered him to submit to a blood test for HIV, as recommended in the probation department's presentence report.

On appeal, defendant sought to have the testing order invalidated because the trial court had failed to state on the record its finding of probable cause to believe that blood, semen, or any other bodily fluid capable of transmitting HIV had been transferred from him to Taylor or to note the finding in the court docket or minutes.

In an unpublished decision, the Court of Appeal affirmed the judgment. With respect to the HIV testing, the court held defendant had forfeited any challenge by failing to object at the time the order was imposed.

DISCUSSION

Penal Code section 1202.1 provides in relevant part that "[n]otwithstanding Sections 120975 and 120990 of the Health and Safety Code, the court shall order every person who is convicted of . . . a sexual offense listed in subdivision (e) . . . to submit to a blood . . . test for evidence of antibodies to the probable causative agent of acquired immune deficiency syndrome (AIDS). . . ." (Pen. Code, § 1202.1, subd. (a).) Penal Code section 1202.1, subdivision (e)(6)(A)(iii) includes "[l]ewd or lascivious conduct with a child in violation of Section 288," but with the proviso that testing shall be ordered only "if the court finds that there is probable cause to believe that blood, semen, or any other bodily fluid capable of transmitting HIV has been transferred from the defendant to the victim: [¶] . . . [¶] For purposes of this paragraph, the court shall note its finding on the court docket and minute order if one is prepared." (Pen. Code, § 1202.1, subd. (e)(6)(A), (B).)

In this case, the trial court ordered HIV testing, but did not make an express finding of probable cause. Nor did the court enter an appropriate notation in the docket or minute order. On appeal, defendant contended these deficiencies rendered the order invalid. Addressing the threshold question of the scope of review, the Court of Appeal applied the analytical framework this court utilized in People v. Scott (1994) 9 Cal.4th 331, 352-356

[ 36 Cal.Rptr.2d 627, 885 P.2d 1040] ( Scott), and People v. Smith (2001) 24 Cal.4th 849, 852-853 [ 102 Cal.Rptr.2d 731, 14 P.3d 942] ( Smith), to determine the cognizability of certain sentencing decisions. In Scott, the court distinguished between unauthorized sentences — those that "could not lawfully be imposed under any circumstances in the particular case" ( Scott, at p. 354) — and discretionary sentencing choices — those "which, though otherwise permitted by law, were imposed in a procedurally or factually flawed manner." ( Ibid.) As to the former, lack of objection does not foreclose review: "We deemed appellate intervention appropriate in these cases because the errors presented `pure questions of law' [citation] and were `"clear and correctable" independent of any factual issues presented by the record at sentencing.' [Citation.] In other words, obvious legal errors at sentencing that are correctable without referring to factual findings in the record or remanding for further findings are not waivable." ( Smith, at p. 852.) With respect to the latter, however, the general forfeiture doctrine applies and failure to timely object forfeits review. Such "[r]outine defects in the court's statement of reasons are easily prevented and corrected if called to the court's attention." ( Scott, at p. 353; see also People v. Welch (1993) 5 Cal.4th 228, 232-237 [ 19 Cal.Rptr.2d 520, 851 P.2d 802].)

Drawing on the analysis in Scott and Smith, the Court of Appeal below found defendant had forfeited his claim on appeal. First, the trial court could have readily corrected the defect in its order upon timely notification. Second, given the uncertainties in the evidence adduced at trial, "whether the trial court could have ordered a blood test depended upon factual issues in the record or requires a remand for further findings." "We cannot substitute for the trial court in reconstructing what happened, which must be based not only on the medical testimony but on the credibility of the testimony as to what happened. This is precisely the type of circumstance that required a timely objection, which would have resulted in a finding that we could review on appeal."

Although we agree with the Court of Appeal's result in this case, we do not adopt the analytical template of Scott and Smith for issues arising under Penal Code section 1202.1.

(1) Since HIV testing does not constitute punishment (see People v. McVickers (1992) 4 Cal.4th 81, 83 [ 13 Cal.Rptr.2d 850, 840 P.2d 955]), it cannot properly be considered a sentencing choice. While the order is made at the time sentence is imposed, the Legislature enacted section 1202.1 and related HIV testing statutes as health and safety measures to combat the spread of AIDS, not to increase criminal penalties. (See, e.g., McVickers, at p. 89; People v. Hall (2002) 101 Cal.App.4th 1009, 1018 [ 124 Cal.Rptr.2d 806].) Instead, we conclude that the general forfeiture rationale applies, and on that basis hold that the failure to make an express finding of probable cause and to note that finding in the docket is not subject to review absent a timely objection.

The forfeiture doctrine is a "well-established procedural principle that, with certain exceptions, an appellate court will not consider claims of error that could have been — but were not — raised in the trial court. [Citation.]" ( People v. Vera (1997) 15 Cal.4th 269, 275 [ 62 Cal.Rptr.2d 754, 934 P.2d 1279]; see People v. Saunders (1993) 5 Cal.4th 580, 589-590 [ 20 Cal.Rptr.2d 638, 853 P.2d 1093]; Doers v. Golden Gate Bridge etc. Dist. (1979) 23 Cal.3d 180, 184-185 [ 151 Cal.Rptr. 837, 588 P.2d 1261].) Strong policy reasons support this rule: "It is both unfair and inefficient to permit a claim of error on appeal that, if timely brought to the attention of the trial court, could have been easily corrected or avoided. [Citations.]" ( Vera, at p. 276.) "`"`The law casts upon the party the duty of looking after his legal rights and of calling the judge's attention to any infringement of them. If any other rule were to obtain, the party would in most cases be careful to be silent as to his objections until it would be too late to obviate them, and the result would be that few judgments would stand the test of an appeal.'"' [Citation.]" ( Saunders, at p. 590.)

(2) This rationale applies with equal force to claims under Penal Code section 1202.1, subdivision (e)(6), that the trial court failed to make an express finding or notation of probable cause. Any deficiencies in this regard are easily remedied upon timely objection. (Cf. People v. Marchand (2002) 98 Cal.App.4th 1056, 1061 [ 120 Cal.Rptr.2d 687] ["if defendant had objected to imposition of the [sex offender] registration requirement on the ground the predicate fact was not alleged in the information, the court could have sought to cure any prejudice from the lack of notice"].) And such procedural defects do not implicate any fundamental or constitutional right that might excuse the failure to object. (See People v. Vera, supra, 15 Cal.4th at p. 276.)

(3) Moreover, the statute neither requires an express finding (cf. Pen. Code, § 1385, subd. (a)) nor contains any sanction for noncompliance. (Cf. Malengo v. Municipal Court (1961) 56 Cal.2d 813, 816 [ 17 Cal.Rptr. 10, 366 P.2d 453] [speedy trial directive under Pen. Code § 1050 is directory only "and contains no provision for the dismissal of a case when its terms are not complied with"].) In this circumstance, we apply the general rule "that a trial court is presumed to have been aware of and followed the applicable law. [Citations.]" ( People v. Mosley (1997) 53 Cal.App.4th 489, 496-497 [ 62 Cal.Rptr.2d 268]; see, e.g., People v. Turner (2002) 96 Cal.App.4th 1409, 1413-1414, fn. 2 [ 118 Cal.Rptr.2d 99]; People v. Martinez (1998) 65 Cal.App.4th 1511, 1517 [ 77 Cal.Rptr.2d 492].) This rule derives in part from the presumption of Evidence Code section 664 "that official duty has been regularly performed." Thus, where a statement of reasons is not required and the record is silent, a reviewing court will presume the trial court had a proper basis for a particular finding or order. (See, e.g., People v. Henson (1991) 231 Cal.App.3d 172, 182 [ 282 Cal.Rptr. 222] [presuming on a silent record that the trial court properly exercised its discretion in imposing AIDS education as a condition of probation].) We see no reason to disregard these principles here.

(4) With respect to notation of the probable cause finding in the docket, nothing in the statutory language or the legislative history indicates the Legislature intended to make validity of HIV testing dependent on an essentially ministerial act. Nevertheless, we admonish trial courts that legislative directives are to be observed even when not mandatory. To the extent a notation in the docket, particularly when accompanied by an express finding of probable cause, focuses the court's attention on the relevant facts, it ensures the ensuing order will be supported by substantial evidence. (See, e.g., People v. Guardado (1995) 40 Cal.App.4th 757, 765 [ 47 Cal.Rptr.2d 81].)

Analogizing to Penal Code section 1385, defendant contends these procedural directives are conditions precedent to a valid order. Section 1385, subdivision (a), authorizes a trial court to dismiss an action "in furtherance of justice" but requires that "[t]he reasons for the dismissal must be set forth in an order entered upon the minutes." Courts have long held that "`[t]he statement of reasons is not merely directory, and neither trial nor appellate courts have authority to disregard the requirement.'" ( People v. Orin (1975) 13 Cal.3d 937, 944 [ 120 Cal.Rptr. 65, 533 P.2d 193] ( Orin).) As we explained in Orin, "The underlying purpose of this statutory requirement is `to protect the public interest against improper or corrupt[fn. omitted] dismissals' and to impose a purposeful restraint upon the exercise of judicial power `"lest magistral discretion sweep away the government of laws."' [Citations.]" ( Ibid.) Thus, the reasons cannot be "merely inferable" from the record because that does "not fulfill the purpose of the statute that the court indicate why its dismissal is `in furtherance of justice' but on the contrary leaves the record vague and subject to speculation as to the reasons for the court's action." ( Id. at pp. 944-945, fn. omitted.)

This requirement is a necessary concomitant of the nature and scope of the discretionary authority Penal Code section 1385 vests in the trial court, which "while broad, is by no means absolute." ( Orin, supra, 13 Cal.3d at p. 945.) Lacking a statutory definition of the "amorphous concept" "`in furtherance of justice'" ( ibid.) and considering the impact of dismissals on the administration of criminal justice ( id. at pp. 946-947), "appellate courts have been faced with the task of establishing the boundaries of the judicial power conferred by the statute as cases have arisen challenging its exercise." ( Id. at p. 945.) Discharging this task would prove impossible without an explicit statement by which to measure the trial court's exercise of discretion against an evolving standard. ( Ibid.)

None of the foregoing concerns and considerations obtain with respect to a probable cause finding under Penal Code section 1202.1, subdivision (e)(6).

(5) To begin, the express terms of section 1202.1, subdivision (e)(6) do not require that the trial court set forth its reasons in an order but only that it note the probable cause finding on the docket. To the extent the court's obligation is substantially more limited in this regard, it is proportionately less significant. Furthermore, a probable cause finding is not an exercise of the trial court's discretion but a determination of the facts in light of an objective legal standard. (Cf. People v. Adair (2003) 29 Cal.4th 895, 904-905 [ 129 Cal.Rptr.2d 799, 62 P.3d 45] [reasonable cause to believe the defendant is factually innocent pursuant to Pen. Code, § 851.8 is objective legal standard].) Accordingly, a trial court's failure to state or note its probable cause finding does not impair or impede a reviewing court's ability to determine the propriety of a testing order. HIV testing also does not implicate the administration of criminal justice. As noted, the Legislature's primary concern in enacting Penal Code section 1202.1 was the health and safety concern with the spread of AIDS.

(6) Unlike the other sex offenses listed in section 1202.1, subdivision (e) (see ante, fn. 3), those enumerated in subdivision (e)(6)(A) can be committed without establishing the medical predicate for possible HIV contraction — the transference of bodily fluids. (See, e.g., People v. Mickle (1991) 54 Cal.3d 140, 176 [ 284 Cal.Rptr. 511, 814 P.2d 290] [touching of child unnecessary; evidence sufficient if the defendant compelled child to disrobe]; People v. Meacham (1984) 152 Cal.App.3d 142, 153-154 [ 199 Cal.Rptr. 586] [evidence sufficient where the defendant instigated children to touch their own genitalia]; People v. Lanham (1934) 137 Cal.App. 737, 740 [ 31 P.2d 410] [evidence sufficient where the defendant removed child's panties].) A finding of probable cause to believe such transference has occurred is therefore necessary to establish the nexus between that medical predicate and an HIV testing order consistent with the defendant's constitutional rights (see People v. Hall, supra, 101 Cal.App.4th at pp. 1021-1022) and the victim's privacy interests. (See People v. Guardado, supra, 40 Cal.App.4th at pp. 764-765.)

Defendant also argues that because Penal Code section 1202.1 implicates the interests of third parties (the victims who might be exposed to HIV infection), an express finding of probable cause and docket notation are mandatory, from which it follows that appeal is not subject to forfeiture. (See, e.g., In re Marinna J. (2001) 90 Cal.App.4th 731, 739 [ 109 Cal.Rptr.2d 267].) Defendant cites no authority that this consideration is relevant under the general forfeiture principle.

(7) On the contrary, third party interests do not constitute a recognized exception, which is limited to deprivation of certain fundamental constitutional rights or acts in excess of jurisdiction. (See People v. Vera, supra, 15 Cal.4th at p. 276; cf. People v. Adames (1997) 54 Cal.App.4th 198, 211 [ 62 Cal.Rptr.2d 631] [the defendant did not object at trial but challenged HIV testing order as ex post facto law].)

(8) We therefore hold that absent an objection in the trial court, a defendant forfeits appeal of any deficiency in the statutorily required finding supporting an HIV testing order pursuant to Penal Code section 1202.1, subdivision (e)(6) or a notation of that finding in the docket or minutes.
