Syphilis Inadequate Screening
Examples are: colonoscopy for colon polyp or cancer; mammograms for breast lesions or cancer; psa a blood test that could indicate enlargement of cancerous prostate tissue; blood sugar or hemoglobin a!c for diabetes. Many think that scanning the whole body will pick up a cancer--in all likelihood, it will not. There also is no good blood test, yet, ...Read more

Depends.: In an normal urinalysis they do not test for stds. But you can use the same urine sample to test for chlamydia or gonorrhea. When they take blood for the syphilis test, the can also test for HIV and hep c, but not for chlamydia or gonorrhea. In summary, to have a "full std panel", you need to give both blood and urine. ...Read moreSee 1 more doctor answer
Yes: There are 2 reasons for this kind of result: (1) a false positive, or (2) early infection before seroconversion. In someone at low risk for HIV without symptoms, another negative WB in 1 month means there's no infection. In someone at risk or with symptoms of acute infection, a viral load can be helpful. The new 4th generation antigen/antibody tests will eliminate this problem. ...Read more
Why is the blood supply screened for syphilis when syphilis is not transmitted via infected blood?
Blood can transmit: Blood contact very rarely can transmit syphilis. It probably requires much more blood than possible during sexual exposure, shared needles, etc, but transfusion can do it, especially with non-refrigerated blood products. It's extremely rare and even without testing, probably there would be few if any cases, at least in the US. OTOH, testing is easy, cheap, and ingrained by history and habit. ...Read moreSee 2 more doctor answers
Is annual STD screening frequent enough to catch potentially asymptomatic STDs (like syphilis) in a timely manner for their treatment? (Not high risk)
Can a pap smear detect the most common std's like chlamydia, genital herpes, HIV infection, gonorrhea, syphilis, trichomoniasis and hepatitis b?
C.trachomatis RNA TMA Result: Detected. Standard range: Not detected. Test performed using the Aptima Combo2 (R) assay gen-probe(r)
You have chlamydia: "Detected" means the test found chlamydia -- i.e. a positive result. Return to the doctor or clinic where the test was done for treatment. (If you tested yourself at a lab, see a doctor or clinic ASAP.) Your current or recent sex partner(s) also need treatment. Good luck! ...Read more
CMIA 4th gen antibody screening test (not antigen) for hiv 1 & 2 @50 days is 0.15 non reactive.Is antibody screening without antigen accurate @7thweek?
Conclusive at 6+ wk: Official advice by many agencies is that stand-alone HIV antibody tests are not conclusive until 3 months. However, with the modern tests in current use, including the test you had, the results actually are conclusive any time 6 or more weeks after exposure. Feel free to have another test at 3 months if another negative result will help you get beyond your fears. But i really isn't necessary. ...Read more
Yes it can: The TPHA test (Treponema pallidum hemagglutination) is a confirmatory test for syphilis. Usually it is done only after a positive screening test, such as the VDRL, RPR, or an EIA test. If you have had negative results on one of these plus the TPHA, you can be 100% certain you don't have syphilis and probably never did. ...Read more
Which of these 3 hep c antibody screening tests(methodology)is the most accurate: Architect Anti-HCV, Advia Centauer HCV or Roche Eclia?
About equal: All three methods are FDA approved and about equally accurate. If you have concern about active Hep C infection, get a Hep C nucleic acid test. 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. ...Read more
Possible: The elisa test can be affected by different infections, causing a false-positive result. After any positive elisa, a follow-up test is performed by a 'western blot' which takes longer to perform, but gives a more sensitive answer. If you or someone you know had a positive HIV by elisa, they absolutely need the follow-up testing (including a full std/sti work up). ...Read more
When the hiv test is conclusive?.what causes repeated perianal fungal infection?last hiv test 14monthes postexposure.is negative?
No worries: Every HIV test that exists, anywhere in the world, is conclusive by 3 months. The most commonly used tests are conclusive by 4-8 weeks. For sure your negative result at 14 months proves you don't have HIV, no matter how high risk the exposure (and if not reexposed), and no matter how typical the symptoms. Entirely healthy people often get perianal fungal infections; it's not a sign of HIV. ...Read more
Can HCV co-infection affect the accuracy of HIV rapid test results? If HIV and HCV antibodies tests are negative at 5 months, are HIV results accurate
It shouldn't: Antibody tests are specific for the antibodies being tested for, so hcv antibodies shouldn't have an effect on HIV antibody tests. If you've tested negative at 5 months, i don't see why those results wouldn't be accurate, but if you want to be sure, you can always wait another 4-6 months and have the HIV test repeated. ...Read more
