Test name:

Test number:

994

Excellian order number:

LAB994

Abbreviation:

MSO

Alternate names:

INSTI
Integrase strand inhibitor
Monogram Integrase Inhibitor Resistance
PhenoSense integrase
Raltegravir

Useful for:

The PhenoSense Integrase® assay is a phenotypic resistance test used to determine the susceptibility of a patient's HIV to integrase inhibitors. Integrase inhibitors block HIV replication by preventing the virus from integrating into the host cell's DNA. Raltegravir (Isentress®) is the first approved drug in this class of HIV antiretroviral drugs.

Specimen type:

EDTA plasma

Collection container:

Lavender (EDTA), 4mL x2

Volume:

3.0 mL

Collection instructions:

Immediately following collection, mix sample thoroughly by gently inverting 8 - 10, times to prevent clotting

Processing instructions:

Spin
Transfer serum to aTransfer vial/tube for small volume specimens (Sarstedt), labelled as EDTA plasma
