3 Week Dna Pcr
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?
Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more
Very reliable.: It's recommended to repeat HIV test on the 12th week or 3 month window to account for a delay in the production of antibodies.If there is a higher risk of getting hiv, it's recommended to repeat the test after 6 months.Take care! http://i-base.info/guides/testing/test-accuracy-results-and-further-testing. http://www.ncbi.nlm.nih.gov/m/pubmed/15967238/ http://hivtest.Cdc.Gov/faq.Aspx#exposure. ...Read more

Fingered with 1day old superficial cut on finger.43daysimmunochromatograohy,49days CMIA antibody,53&57days DUO CMIA P24 all negative.Further test req?
Laceration: Not sure why you listed all of the blood tests. If you are immunocompromised for any reason (cancer treatment, chronic infection like HIV, or TB, or other chronic illness) an seemingly simple laceration can pose a risk of infection. Treatment superficial cut should include cleaning the wound daily with soap and water and coverage with an appropriate bandage. IF redness develops seek treatment. ...Read more
Need details: A single nucleic acid test after the interval during which this becomes positive is proof enough that you are not infected. You're young. I trust you'll play safe from now on, and if you continue to have obsessive thoughts that you have become infected, sit down with your physician or someone who's trained in helping you get back into control of these unwanted and unhelpful thoughts. ...Read more
05/05/2016 Siemens Advia Centaur hep C antibody result positive.08/10/2016 Abbott Architect (cmia) hep C antibody result negative.Who is telling truth?
It's not really: a question of truth telling. No test is perfect: the proteins and reactants used in each test will respond to an individual's blood/biologic material, potentially, in a different way. Falsely positive or falsely negative results are not very unusual. You need to decide on a confirmatory strategy with your doctor. Retesting is necessary and an expert can help you weigh the evidence to decide result ...Read more
Are 3 negative HIV rapid tests done 1yr, 2yrs, and 3yrs after protected sex, conclusive of not having hiv?
ANA via ELISA 74 units, strong positive (negative via IFA)
Anti-Cardiolipin IgG 22 CU, moderate positive
Short answer is : Needing more info on labs and clinical symptoms. ANA positive is sensitive for possible autoimmune disease.but not very specific. Every lab on your ENA panel is important esp they are moderate positive and they all mean something different. Lab is never enough for diagnosis esp rheumatic condition. It is important for you to find a rheumatologist for thorough history and physical exam. ...Read more
Took a quantitative blood test this week, 9 weeks after sexual activity, came back < 0.6 hcg, Ovulation test positive 4 days later. Am i pregnant?
Oroquick: There are no tests that are foolproof and which do not have some percentages of false negative results. If you have had a potential exposure to HIV you should go and be tested using the 4th generation antibody testing techniques, or if you can afford it, get pcr for HIV rna. Suspect it will be negative, but better safe than sorry. ...Read more
Testing for HBsAg can give false positive after vaccination. Is it the case with Hepatitis B PCR also? Does vaccination affect DNA PCR result also?
Hepatitis B antigens: Positive hepatitis B antigens found in the blood are sign of infection, but antibodies to the antigens are signs of protection. Other antibodies are found in the beginnig of the infection. The vaccination is very good, but someindividual might not respond or might need repeat vaccination. ...Read more
Results: Hep C quant. : 2,802,680
HCV log10: 6.448. Reflex to genotype was unable to determine genotype even though there was sufficient HCV RNA?
Hepatitis C virus: Sometimes it's not possible to determine the genotype of this virus, which thus makes the expected response to treatment more uncertain. This is a 'slippery virus' -there are 11 major genotypes (designated 1-11), and many subtypes (a, b, c, etc.) A hepatologist (GI subspecialist) or an ID doctor who works with Hep C patients can help you. You'll need an established relationship for treatment... ...Read more

I'm hebs ag negative with a high anti hbs antibody from vaccination. This week's test was reported as hebs ag detected with anti hbs antibody of 513 miu/ml. Lft normal....Scared....Lab error?
Yes: That sounds like lab error. Your hbsab would provide immunity; i'm assuming yoru hbcab (core) is negative; i wouldn't worry, talk to your doctor about a retest if you are concerned, but even if you were infected, there is no reason for treatment at this time. ...Read more
