HIV-1 viral load (Molecular Microbiology)

General information

Collection container (including preservatives): CE marked leak proof container

Specimen type: EDTA Blood, CSF

Collection: Freshly drawn whole blood in EDTA

Specimen transport: Ambient or refrigerated

Turn round time for provisional result (working days): 4 days

Turn round time to final result (working days): 5 days

Clinical information

Clinical decision points: Not applicable

Factors known to significantly affect the results: False negative results may occur for a variety of reasons, for example inappropriate timing of sample collection, inappropriate sample, presence of virus below the detectable limit of the assay. New and emerging variants may also occur which may not be detected by this assay. Towards the limit of detection of an assay sampling variation will result in lower reproducibility.
