The Enzyme-Linked Fluourescent Assay (ELFA) is a slightly newer version of the Enzyme-Linked Immunosorbent Assay (ELISA) test. Both work in a similar way but the ELFA has a window period which is about 5 days shorter than the ELISA test. Both are very accurate. This means your results are conclusive. You do not have HIV.
My husband had positive elisa test with 3.45 value in august 2016 for hepatitis c. Then he got treatment aND it showed 0.85 value in January 2017. He got checked his hepatitis C by elisa test again two days back. It showed a value of 85.0. He's active n doing job. No cough or any other symptoms. He did it as just a routine checkup. Please guide if elisa test can be 85.0 ?? What should we do next? Much worried! !
The Herpes Simplex IgG test is performed using an ELISA (Enzyme Linked Immunosorbent Assay) test kit manufactured by Euroimmun Diagnostics (Germany). This ELISA test provides a quantitative in vitro assay for human antibodies of the IgG class against HSV 1/2 (group specific) viruses in serum or plasma.
Enzyme-linked immunoassay (ELISA) or enzyme immunoassay (EIA): The ELISA (also referred to as EIA) detects antibodies against recombinant HCV antigens. "First generation" ELISAs used a single antigen; later tests added additional antigens.146-148 Second and third-generation tests are both in standard use.
hi sir my elisa test after 5months report is negative and my reoprts description is this
SEROLOGY
Test Description Value Observed Biological Reference Interval Accreditation
HIV 1 & 2 0.60 Index Value
Non Reactive: Index Value = 1.0
Interpretation
Non Reactive result implies that no Anti HIV -1 or Anti HIV -2 antibodies have been detected in the sample by this method.
That's a decription of the ELISA test method that is common in commercial testing.
10/14/08(after exposure 25 days),RNA loading,CD4/CD8 ratio and liver enzyme activity,CBC,HIV antibody, all normal.
10/30/, 11/15, 11/25, 12/10, Home access kit, EIA test negative.
11/22, my girlfriend using Home access kit, EIA test negative.
11/25, RNA loading PCR, negative.
12/10 (12 weeks after exposure), Elisa test positive, but Western blot(three antibodies) show negative.
Doctor ask me one month later to see him again.
So many tests I did, and gave me so many axiety.
At how many weeks after a possible exposure a negative anti HCV (ELISA) test can be considered conclusive?
Is the ELFA test method an improved ELISA (as explained by the doctor at Apollo) and is it a Duo test/4th generation test?
3> Do I need to get another ELISA done at a different lab?
Appreciate you response.
Thanks,
Hivedoff
P.S: I have already sked a few related questions in the doctors forum, which have been kindly answered by Dr. EWH and Dr.HHH. But, I wanted a more specific answer about Apollo Hospital and if the ELFA test in India is approved ?
Don't overthink it. ELISA is the main technology worldwide for HIV testing and the test methods are virtually foolproof, regardless of where they are done. You definitely should stop worrying.
