Hepatitis B Archives - Infectious Disease Advisor

Although sensitivity is an important consideration when deciding among HIV tests, there are other factors to consider, such as test invasiveness, available resources, need for additional studies, and patient adherence.6 Serum- and plasma-based HIV testing is the most invasive and requires the most resources, such as access to a skilled clinician or phlebotomist and access to special equipment (eg, needles, biohazard containers, laboratory). Whole blood testing can be performed by venipuncture or finger-stick. When blood-based tests yield a sufficient specimen sample using venipuncture, additional studies can be undertaken, such as HIV subtyping and assessment for coinfections, including hepatitis or syphilis. In contrast, oral fluid tests do not require special equipment and can be performed in any setting, including at home, providing results in minutes. These tests also eliminate safety and biohazard concerns, such as needlestick injuries and sharps disposal.
