Why PCR isnt good test for HIV diagnosis? Is it high Cost or low Accuracy?
PCR RNA is better or DNA @ 6 mnth?
Neg 3 DNA & 1 RNA PCR are 100% accurate?
To what extent is duo test (p24 and elisa) for hlv infection accurate and reliable after four weeks of sexual relation?
I had unprotected sex 10 weeks ago.
I did Elisa 4 generation- negative.
PCR - <40 (undetectable)
I can be sure I don't have hiv?
Not yet: To be sure, you should repeat these tests at 6 months after exposure, just in case of delayed response. The chances are good that you are HIV free. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. ...Read more
My bro wants to know if duo test (p24 and elisa) is accurate after 4 weeks of exposure? Plz help him he is so worried.Thank u
Two better than one?: The duo test looks for the p24 antigen or protein made by the HIV virus. The elisa tests for the body's immune response to the infection (antihiv antibodies). Elisa is now very sensitive & specific (>99%/>99%) but can take 3-6 weeks to become (+). The p24 antigen may be positive faster (in studies 1-2 days on average being (+) @28d ) & may be more sensitive in diagnosing very early infection. ...Read more

Two ELISA HIV tests at 4 and 12weeks negative.CBC test WBC left shift.have body inflammation and flu almost for 12Weeks.what does it mean?
Need antibiotics: Two negative HIV test s is reassuring that your current status is negative. A 'left shift' is a general term that is used to describe changes in the WBC patterns that suggest an active bacterial infection. Were all other STD screens performed and negative? Bacterial infections are treated with antibiotics. ...Read more
2 weeks exposure to: what? Please clarify & re-ask.Get a more detailed answer ›
Radiation-free test: Elisa is a test that detects a foreign substance (antigen) or an antibody in blood. Elisa uses an enzyme bound to a 2nd antibody . In the final step the enzyme converts indicator material to a different color. The amount of color detected corresponds to the amount of antigen or antibody present. Elisa gives the same answer as rast without using radioactive radioisotopes. ...Read moreSee 1 more doctor answer
Repeat after 4 weeks: Most viruses if you are infected withhiv will not show positive test untill six weeks, but if negative needs ti be repeated at 12 weeks.If elisa test is negative at 12 weeks than you can be confident good luck but i advice that you ue protection if there is risk of exposure and play it safe.And if you have high risk exposure consult doctor and they can prescribe preventive meds cocktail. ...Read more
I was tested today with elisa and the titre was 0.253 ,positive was> 1.0 while negative was<1.0 what is my result?
Negative: The number 0.253 (just round it off to 0.2) is less than 1, which is Negative according to the reference range stated in the question. Of course, numbers are just numbers, and the clinical meaning of a number or a Negative value must be interpreted in the context of a patient's real-life situation. ...Read more

I have heard different estimates on what the viability is for blood that is going to be tested via elisa test. I've heard that you should get the sample tested within 3 days 7 days 14 days and up to 30 days if blood is frozen. What is ideal?
After exposure, 3months HIV quali RNA test negative, not detected.4.5months HIV quick test and ELISA test negative.Are those tests all exclusive?
No: If positive, it will be followed up with a confirmatory test. If negative, you are almost certainly okay but if you are very worried you might be able to pay for a pcr assay, which is the gold standard. ...Read more
How do you know HIV: If HIV antibody testing is negative through elisa how do you know the person is hiv+? If they have been shown to have HIV by PCR testing for viral RNA it is possible, but unlikely, that their immune system is so impaired that they cannot form antibodies. It is also possible, but again unlikely, that they have HIV type ii and not being tested for this. Something does not make sense. ...Read more
Unreliable test: Refers to a test that determines the presence of antibodies against the influenza virus. It has a very inconsistent sensitivity rate, and can potentially read a negative result in a patient that actually does have the flu. Superceded by molecular techniques that are more accurate but expensive to administer. ...Read moreSee 1 more doctor answer
What are probabilties to have HIV after testing negative in a 4th gen ELISA 30 days after exposure?
I have to take a ELISA test today for Lyme disease but i was just wondering how does ELISA test work?
Sandwich assay...yum: Elisa = enzyme-linked immuno sorbent assay. Done by adding serum from a subject to a plate w/antibody against the infection you're testing for on its surface. The antigen (or protein) from the infection binds to the antibody on the plate. Then another antibody to the infection w/color signal chemical attached is added on top and binds to the antigen. If infection is there color can be measured. ...Read more
If there is a cross- reactivity during an elisa test is it possible to end up with a false negative as a result?
False positives: Cross-reactivity can cause false positives (meaning that the test is positive but the actual substance tested for isn't there). The happens when an antigen (virus, protein or bacterium) is so similar structurally that it reacts with the same antibody that the test is designed for. For example, the antibody test for latex allergy can sometimes cross react with a protein in bananas! Crazy, huh? ...Read more
What to do if I have to take a ELISA test today for Lyme disease but I was just wondering. 1. how does ELISA test work?
Elisa test after 3 weeks&5 weeks negative. Only deep French kissing no penteration at all. Is it OK or not enough .I'm really worry?
No risk at all: Presumably you're speaking of HIV risk and testing. You were not at risk and did not need testing; HIV is not transmitted by kissing, deep or otherwise. (HIV is not transmitted by saliva.) And if your ELISA was for the antigen-antibody (4th generation) test, the 5 week result is conclusive. If a stand-alone antibody test, the results are over 95% conclusive, maybe have a final test at 6 wk. ...Read more
2 ELISA tests for HIV done at 3 months and 6 months of exposure, is it a conformation that I dont have HIV if both tests are negative?
Almost certainly: The ELISA tests detect antibodies to HIV and can appear as early as 2 weeks after infection but, if not detected by 6 months, it's 99% certain that you haven't been infected. That doesn't necessarily mean you weren't exposed however, It could mean you were lucky. Stick with protected sex unless you are at least 99% certain your partner isn't infected either. ...Read more
I have been diagnosed with lots of food intolerances (using an ELISA food panel). Other than feeling bad, what happens to my body when i eat them?
Inflammation &stress: Food allergies can cause virtually any symptom: headaches, muscle, joint & abdominal pains, anxiety, depression, palpitations & fatigue. Antibodies react to food proteins in your body causing an inflammatory response that can contribute to arthritis, cardiovascular disease& osteoporosis, accelerates aging & stresses adrenals.By avoiding allergenic foods & treating candidiasis, intolerances go away. ...Read moreSee 1 more doctor answer
I was tested RPR and tppa test and elisa, with negative results but in rapid test with immunochromatographic assay i was reactive, what does it mean?
No syphilis: The newer syphilis blood tests, including the rapid tests, measure IgG antibody. They often give false positive results. The current consensus among STD and syphilis experts is that syphilis is not present when the RPR and standard confirmatory tests (e.g. TPPA) are negative, regardless of rapid or IgG tests. In your case, you also have a negative ELISA test. You definitely on't have it. ...Read moreSee 1 more doctor answer
