The petitioner, Jonathan Carvalho, appeals from a judgment of a single justice of this court denying his petition pursuant to G. L. c. 211, § 3. We affirm.

Carvalho was indicted for murder and unlawful possession of a firearm. The Commonwealth moved to compel Carvalho to provide a buccal swab on the basis that it needed deoxyribonucleic acid (DNA) evidence to try to exclude Carvalho as a possible source of blood found on his sneakers. Over Carvalho's objection, a judge in the Superior Court allowed the motion. Carvalho thereafter filed his G. L. c. 211, § 3, petition in the county court.

The case is now before us pursuant to S.J.C. Rule 2:21, as amended, 434 Mass. 1301 (2001), which requires a showing that "review of the trial court decision cannot adequately be obtained on appeal from any final adverse judgment in the trial court or by other available means." S.J.C. Rule 2:21 (2). Carvalho has not made such a showing. As he recognizes, this court has rejected the argument that he will not be able to obtain adequate review on appeal from any conviction because the seizure of his DNA, through the buccal swab, will have already occurred. See White v. Commonwealth, 439 Mass. 1017, 1017 (2003), and cases cited. Carvalho therefore seeks to raise an additional argument -- that he cannot obtain adequate review on appeal from any conviction because once his DNA profile is obtained, it "will be immediately available to the Government for comparison with DNA profiles obtained from other crime scenes, potentially requiring [him] to defend other unrelated charges as a consequence of the seizure in this case." He did not, however, raise the argument before the single justice. We therefore need not consider it. See, e.g., Kartell v. Commonwealth, 437 Mass. 1027, 1028 (2002), citing Milton v. Boston, 427 Mass. 1016, 1017 (1998).

Judgment affirmed.

The case was submitted on the papers filed, accompanied by a memorandum of law.

Willie J. Davis for the petitioner.

Romiules Bonilla (defendant), facing multiple drug charges in the SuperiorCourt, moved to suppress the evidence. A judge in the Superior Court denied his motion. The defendant next applied to a single justice of this court for leave to pursue an interlocutory appeal from the suppression ruling. See Mass. R. Crim. P. 15 (a) (2), as appearing in 422 Mass. 1501 (1996). The single justice denied the application. The defendant now purports to appeal to the full court from the single justice's ruling.

This "appeal" is not properly before us. "Neither the Commonwealth nor a defendant may appeal to the full court from a single justice's denial of an application for leave to pursue an interlocutory appeal." Cowell v. Commonwealth, 432 Mass. 1028, 1028 (2000). The defendant can challenge the suppression ruling in a direct appeal, after trial, if he is convicted.

Appeal dismissed.
