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.

Compliance Statement D: This test was developed and its performance characteristics determined by ARUP Laboratories. The U.S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

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.
