Question 1

which hiv test is used for screening blood for transfusion (blood donor) ?

Accepted Answer

: PCR (to detect HIV RNA) and an antigen-antibody (AgAb, "4th generation") test. Because they are so effective, there have been no transfusion-caused HIV infection in the Us for many years.

Question 2

as the insertive circumsized partner in heterosexual sex, without anal or blood exposure, is my risk of contracting htlv as low/lower than hiv? (no ones tested for htlv unless theyre a blood donor or in a study?

Accepted Answer

: Risk of contracting HTLV is lower than HIV if your partner is infected and risk of developing the disease is much, much lower; only 2 to 6 percent of people infected with HTLV-1 will ever develop an illness.

Question 3

can a patient receiving multiple blood and plasma transfusions test positive for thc if the blood donor had recently used marijauna?

Accepted Answer

Not likely: The amount of thc in blood or blood products is not likely to cause a positive urine test. You are more likely to get a positive test from exposure to second hand marijuana smoke.

Question 4

i was deferred from the blood donor service for testing positive for hep b. i am a virgin. i do not take drugs. i have never been admitted to hospital or received a transfusion. could this be a mistake? what else could i have?

Accepted Answer

See your Dr.: See your primary care Doctor. They can perform a test for Hep B and look at your liver enzymes, etc to determine if the test on your blood was accurate and to discuss where you may have caught it if it is positive.

Question 5

a blood donor suspected case of hep c got 2 anti hcv test done 1. value 0.06(cut off 1.00) 2. value 0.869(cut off 0.361) sgot 33 sgpt 35.advice?

Accepted Answer

Hcv viral load: The anti hcv titer by different methods can fluctuate and also it can fluctuate in the same person at different times. In these cases the most reliable and confirmatory test would be a quantitative hep c viral load by pcr. Hope this helps.

Question 7

how blood donations are screened against hiv-2? can modern screening methods catch hiv-2 if donor is in his acute period (i.e 14 days after exposure)

Accepted Answer

Hiv screen in blood: Blood donations are screened for HIV 1 and HIV 2 by enzyme immunoassay (EIA) followed by one or more confirmation tests. The windowperiod between infection and the detection of antibody by about 4-7 days.

Question 8

will any vaccinations exclude a person from being a blood donor?

Accepted Answer

MMR, Chicken pox and: Mmr, varicella (chicken pox) and yellow fever all have a 4 week waiting period until blood can be donated.

Question 9

i am a blood donor and have been told that i am a bromelin auto. what does it mean?

Accepted Answer

Nothing: This is a lab curiosity that may make it a bit more tricky for the blood bank to be sure that your blood is safe for the next person.  It should have no health implications to you.

Question 10

my partner is a regular blood donor and has frequent medical check ups. does this imply that he is stis safe?

Accepted Answer

Not fully: Blood donors are only screened for conditions transmitted via blood (hiv, hepatitis, etc.). There are other potentials (gonorrhea, chlamydia, etc.) that are not screened for, and potentially could be present. Condoms always best choice.
