A potential donor is angry at the personal nature of the questions about HIV risk factors that he is required to answer at a blood collection center and states that simple blood testing should suffice. How can the nurse at the center best respond?
A)
"There are some very uncommon subtypes of the HIV virus that are not detectable by current testing methods."
B)
"There's a chance that persons who are asymptomatic, but HIV positive can have their antibodies missed by serum testing."
C)
"There's a period shortly after someone is infected with HIV when blood tests might still be negative."
D)
"Even though blood tests are completely accurate, the high stakes of blood donation and transfusion mean that double measures are appropriate."
Ans:
C
Feedback:
The time after infection and before seroconversion is known as the window period, during which HIV antibody screening may be negative. Potential donors are thus screened to identify potential risk factors. Undetectable subtypes of HIV do not exist, and individuals who are asymptomatic are still able to be accurately tested.
