Specimen Type Describes the specimen type validated for testing

Plasma EDTA

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Draw blood into two 5 mL PPT (pearl top) or EDTA (lavender top) tube(s). Immediately centrifuge (within 2 hours of collection) at 1000 – 1200 x g at room temperature for 10 – 15 minutes. Do not allow samples to remain in centrifuge after centrifugation. Remove plasma from cells immediately and transfer to a plastic screw cap tube. Freeze immediately. Send 3 mL plasma in a screw-cap vial frozen.



1.     Patient's most recent viral load.

2.     Viral load collection date.


NOTE:  1. Intended for use only for patients with viral loads greater than or equal to 500 copies/mL. For best results, viral loads should be confirmed within 2 weeks prior to submission for testing at Monogram.

2.Patient samples submitted <30 days apart are considered duplicate and will be cancelled.

Specimen Minimum Volume The amount of sample necessary to provide a clinically relevant result as determined by the Laboratory.

1 mL
