I had a question about HTLV testing. How accurate is it?

Customer Question

I had a question about HTLV testing. How accurate is it? Does it give a lot of false positives or is that very rare?

Hello,
Usually the screening test is done by enzyme immunoassay and if the screening test is reactive then blood has to be retested with a confirmatory test, a Western Blot.
The test used by blood bank reference laboratories are highly accurate. In a study (0.7%) false-positive cases were identified.
I hope this helps

7% of them were false positives? That's quite high isn't it? Also, what would cause a false positive? Would the hpv vaccine cause a false positive?
Expert:  Dr. Anil replied 1 year ago.

Kindly note it is 0.7% and not 7.0%.

Expert:  Dr. Anil replied 1 year ago.

Influenza vaccination is related to false positive results..

Customer: replied 1 year ago.
My mistake, sorry. So an hpv vaccine shouldn't affect the test?
Expert:  Dr. Anil replied 1 year ago.

Less likely.

Expert:  Dr. Anil replied 1 year ago.

No such published study.

Expert:  Dr. Anil replied 1 year ago.

Usually positive results by ELISA should be confirmed with more accurate western blot test which is a confirmatory test.

Customer: replied 1 year ago.
I'm just scared of taking the test and getting a false positive
Customer: replied 1 year ago.
do most people usually screen for this disease?
Expert:  Dr. Anil replied 1 year ago.
Hello,
I understand your concern.
In my opinion,you shouldn't worry about testing.
And it's good to go for testing rather than worrying.
Most likely your results would be accurate.
I hope this helps
