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.
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.
The enzyme-linked immunosorbent assay (ELISA) screen is often the first test performed. It tests for HCV antibodies that the body has produced in response to the infection.
enzyme immunoassay (EIA), radioimmunoassay (RIA), magnetic labels (MIA), Enzyme-Linked Immunosorbent Assay (ELISA).All of the above mentioned methods (including ECLIA) are quite reliable. ECLIA is not the same as ELISA, because they have different substances attached in order to detect the substance that is checked for.
I'm trying to go UAE and went to UAE embassy authorized diagonisis center. They checked HCV and informed HCV is "reactive" in my blood.
After that I went to 4 diagonisis center in my native and first 2 center tested HCV by card method it's showing "negative", 3rd center tested anti HCV antibody by serum/enzyme linked immunosorbent assay (ELISA) method its showing "Non-reactive(0.
The Red Cross site says they use enzyme-linked, immunosorbent assay (ELISA). Here is a chart that shows various HCV Antibody assays.

The liver is located on the upper right. Here is a chart (thanks to Hector) that shows what's in the left upper quadrant:

So I needn't worry and take my results as conclusive ?
You can opt for specific tests for Chlamydia which include Nucleic acid amplification tests (NAAT, to find the genetic material of Chlamydia), Nucleic acid hybridization tests (DNA probe test, Enzyme-linked immunosorbent assay (ELISA, EIA), Direct fluorescent antibody test (DFA) or chlamydia culture.
I hope it helps. Take care and regards.
To determine if hepatitis C antibodies (HCAb or anti-HCV) are in your blood, doctors use a screening test called ELISA, which stands for Enzyme-Linked ImmunoSorbent Assay. There are many different ELISA tests, so doctors must use one specifically for hepatitis C. The ELISA test will search the blood sample for the hepatitis C antibody. If any are found, this means that you might have HCV infection.
Else you can opt for specific tests for Chlamydia which include Nucleic acid amplification tests (NAAT, to find the genetic material of Chlamydia), Nucleic acid hybridization tests (DNA probe test, Enzyme-linked immunosorbent assay (ELISA, EIA), Direct fluorescent antibody test (DFA) or chlamydia culture. If these tests come up positive then one will need to look at other possibilities.
I hope it helps. Take care and regards.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.

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.
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.

Hence it would be wise to opt for specific tests for Chlamydia which include Nucleic acid amplification tests (NAAT, to find the genetic material of Chlamydia), Nucleic acid hybridization tests (DNA probe test, Enzyme-linked immunosorbent assay (ELISA, EIA), Direct fluorescent antibody test (DFA) or chlamydia culture.

There are different HIV antibody tests. One test is the ELISA (enzyme-linked immunosorbent assay). If the ELISA test is positive, a second test called a Western blot is done to confirm the result. The Western blot takes longer to perform and is more expensive than the ELISA test, but it is more precise.
