Microscopic If Positive
Latent TB: An interferon gamma release assay like quantiferon is a improvement over the old TB testing. A positive means you have been infected with TB but may or may not have disease. A chest xray is the next step to see if you have any lung involvement. In addition an exam to rule out any lymph node or other involvement is needed. If exam and x-ray are normal you have what is termed latent TB infection. ...Read more
Urine tests for STD: Yes. But, the doctor has to order this test and it may require a special tube to transport the urine to the lab. If you did not discuss this with your provider you may still be able to have this test added to your labs if you phone them and express your concerns. But, when you are at the doctor's office please remember to state all of your questions or concerns. ...Read more
I did do a urine culture sample and it was negative does that test detect if there's a wbc in your urine or urethra?
Time to move on: Sigh. You're grasping for straws. This test itself doesn't detect WBC. But you've already had that test anyway. Please stop asking further on line. You'll never get more clear ansswers than you have had. Work with your own doctor. Best wishes. ...Read more

Is it possible to still carry chlamadyia infection despite a negative result in PCR Dna test??(symptoms persist)
Very unlikely: The chlamydia DNA tests are very accurate; a negative result is good evidence the infection is gone. Chlamydia symptoms in women (e.g. vaginal discharge, painful urination, etc) are nonspecific, i.e. same symptoms caused by many different conditions. Return to your doctor or clinic to evaluate the cause and treatment of your continuing symptoms. Probably it isn't chlamydia. Good luck. ...Read more

Yes: Proper sampling will yield the result.Get a more detailed answer ›
Yes: There are a variety of other causes of granulomatous disease in the gut; half of crohn's cases don't show granulomas in the first place, and i suspect no pathologist would make the call except upon examining the clinical and imaging findings as well. The diagnosis of crohn's, and the decision how to treat, is usually made by collaboration among physicians. ...Read more
Is a high swab vaginal herpes DNA test result reliable? (Without leison) Do I need another blood test to reconfirm?
Not reliable: Any single swab test for HSV only shows the virus was not present at that moment. Even in people with proved genital HSV2 infection, virus typically is detectable less than 20% of the time; for HSV1 it's under 1% of the time. So this test doesn't show whether or not you have genital herpes. A blood test can help: if positive for HSV2, you have genital herpes, regardless of swab test results. ...Read more
No: Lukas, you're a grown man now and you recognize that you have health concerns that are unrealistic. In a way it's good -- you'll be more vigilant -- but if these fears are preventing you from finding the peace you need to work, play and love, then some structured self-exploration might set you free. Be brave, and best wishes. ...Read more
If bag for babies urine sample was contaminated can high level of white blood cell test be false?Also second bag for culture make test false neg?
No bags!!: If there is a significant concern for a urine infection in a baby, a bag specimen should never be used. It's akin to pooping on an area before a culture is collected instead of a nice sterile clean sight. The baby should be catheterized with a tiny feeding tube or small cath tube and a truly clean specimen obtained. So many false positives from dirty specimens and then unclear results. ...Read more
Maybe: Leukocytes (white blood cells) are found in urine when there is any source of irritation (uti, stones, tumors...). Nitrites in urine are generally due to bacteria that make nitrites, but not all bacteria do so. The only way to be sure you have a UTI (and know how best to treat it) is to have the urine cultured, which means it is grown in a lab for 48-72hrs, then tested with several antibiotics. ...Read moreSee 1 more doctor answer
Culture: A culture is more sensitive for smaller amounts of infection not easily seen by smear, but it does usually take a bit longer. ...Read more
Can someone that tested negative on a HIV test still pass it to their partner?
If later they test positive...
No protection? Yes!: The viability of the virus may be less established if the partner's infection was too new to show, but less is not none. You certainly should also be tested by a reputable clinic and avoid unprotected sex in almost any situation. Hiv & other stds are very serious! i imagine you drive, so i'll make this road safety comparison: use turn signals by habit, don't decide if it's necessary - it is! ...Read more
