HIV Qualitative & Quantitative; Both Ordered

Slide 5

September 2010

At Mayo Medical Laboratories, we do a lot of HIV testing and one problem that we encounter is that we often receive requests, on a single patient, for both the quantitative HIV test, as well as the reflex test that first quantitates HIV levels and then reflexes results >1,000 copies/mL to HIV genotyping. Genotyping is used to help physicians know if a patient is likely to be susceptible to standard drugs. We are not sure why this particular duplicate order occurs so frequently, especially since our test catalog indicates 3 options:

  1. Quantitative viral levels,
  2. Genotyping, and
  3. Quantitative and genotyping together.

Our accessioning team screens these orders and when these tests are ordered together, we cancel 1 of the tests and perform the reflex test, sparing the patient the charge for the duplicate order. You can do your part by understanding the components of reflex tests and making sure that redundant orders are not passed on.
