Reference Interval
By report
Interpretive Data
The entire integrase-encoding region is sequenced. Mutations associated with resistance to integrase inhibitors are reported. Mutations in viral sub-populations below 20 percent of total may not be detected.

See Compliance Statement D: www.aruplab.com/CS
Note
This test may be unsuccessful if the plasma HIV-1 RNA viral load is less than 500 HIV-1 RNA copies per mL of plasma.
