This answer was rated:

My Hep-2 Cell test result is 40 Titer. It shows a Flag A and then in the reference says negative at 1:40. So is my 40 normal, low, not sure how to interpret?
Dr. Shahzad MD :

Hi there. Thank you for your question. I will be helping you out with your queries

Dr. Shahzad MD :

The test is negative

Dr. Shahzad MD :

1:40 would be interpreted as a negative test result of hep-c test.

Dr. Shahzad MD :

Let me know if you have any further questions.

Customer:

Why did they put an A under the Flag category?

Dr. Shahzad MD :

Its a computerized thing. Not sure how that A came in there.

Customer:

So why didn't the result show 1:40 versus just 40. Or does this mean it's normal if you're in the range of 1-40?

Dr. Shahzad MD :

I think that your test was done by the ELISA technique

Dr. Shahzad MD :

which is why they gave a number rather than dilution i.e. 1:40

Dr. Shahzad MD :

The normal range for the ELISA is different

Dr. Shahzad MD :

have they given a different range for it?

Dr. Shahzad MD :

or just one range

Customer:

It shows Test Name Hep-2 Call, then a result column that says 40 Titer, then a column that says Flag is the letter A under it and then a reference line with Negative at 1:40 under it. I guess the part that is bringing this question to light is the A under the Flag column. Under all the tests I've had done nothing shows under the Flag column except B12 which is and H under the Flag line and the number is ***** above the reference numbers given.

Dr. Shahzad MD :

The textbook normal range is something like this:
"and any value less than or equal to 1:40 dilution (or < 1/0 IU) is negative." So you are negative as far as I am concerned.

Customer:

Thank you for your help. Have a nice evening!

Dr. Shahzad MD :
