Probably: However, it is too soon to tell. If you had high risk exposure you should discuss prophylactic treatment with your doctor. It may take up to six months for HIV infection to manifest itself, so you should repeat the tests in 6 months. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

What is the likelihood of a false negative on a PCR RNA TMA HIV test at 15-20 days post PEP/post exposure? I have heard of false positives.

What is the likelihood of a false negative on a PCR RNA TMA HIV test at 15-20 days post PEP/post exposure? I have heard of false positives.

Too soon to rule: out HIV. The PCR RNA test if negative at about 3 months after exposure would rule out infection. A negative result before than may not be definitive. A positive result be definitive any time. ...Read more

Paranoia about HIV exposure. 4th Gen test, negative at 9th, 17th, and 37th day. RNA QL TMA early test, negative at 17th and 37th day. Can I rest easy?

Paranoia about HIV exposure. 4th Gen test, negative at 9th, 17th, and 37th day. RNA QL TMA early test, negative at 17th and 37th day. Can I rest easy?

Rest easy: There are 2 types of HIV tests, viral antibody tests are the most common and inexpensive. 95% of people who have contracted AIDS show positive within 90 days, but it can take 6 months. Then there are tests looking for the virus itself (viral load) these will be positive within 2 weeks or sooner. These are the early tests such as RNA QL TMA. Based on that, Be safe and relax. Good health ...Read more

First unprotected sex on 9th June. Antibody test on 14th June & 14 July. Aptima HIV-1 RNA, Qualitative, TMA on 20th may. All negative.Should I worry?

Repeat in 6 months: Just to be sure repeat the HIV nucleic acid test 6 months after the June episode. I trust you got tested for other STDs as well. Wish you good health. ...Read more

Please interpret- C.trachomatis RNA TMA Result: Detected. Standard range: Not detected. Test performed using the Aptima Combo2 (R) assay gen-probe(r)

Please interpret-
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

Will alprazolam show a false positive for nordiazepam and or oxazepam. The confirmation test was done via gc/ms from the lab i use. ?

Will alprazolam show a false positive for nordiazepam and or oxazepam. The confirmation test was done via gc/ms from the lab i use. ?

Probably yes: My educated "guess" is that most drug blood screening is geared toward "groups" or "classes" of substances. Alprazolam, diazepam, lorazepam, and the others you mentioned are all considered to be in the class of benzodiazopine derivatives. Use of any of them will trigger a positive response, but is not specific to which is in your system. Other classes include thc, cocaine, crystal meth, etoh, etc. ...Read more

Ngu oral sex. Chlamydia, gc, myco gen neg. 1 swab was 7wbc. wife took doxy & I took aizthrmycin 1g. swabs since <5wbc. Never discharge or pain. Ngu?

Ngu oral sex. Chlamydia, gc, myco gen neg. 1 swab was 7wbc. wife took doxy & I took aizthrmycin 1g. swabs since <5wbc. Never discharge or pain. Ngu?

Unclear treatment: If you and your wife’s tests are all negative indicating no infection then it is unclear to me why antibiotics were given. Doxycycline and Zithromax in those doses are standard treatment for chlamydia yet both of you were negative. Treatment should not be based on WBC alone especially given that you have no symptoms. Clarify the underlying problem trying to be addressed please. ...Read more

What could cause me to test positive for methamphetamine and amphetamine on a urine drug test that was confirmed using gc-ms when I do NOT use drugs?

What could cause me to test positive for methamphetamine and amphetamine on a urine drug test that was confirmed using gc-ms when I do NOT use drugs?

What DO you take?: Someone else's specimen may have been mislabeled as yours. Or, you may be taking a medication that is "cross-reactive" with amphetamines and caused a false-positive result. Labs usually include such cautionary information in their reports. Go over the lab report and your meds with the ordering physician. ...Read more

Have on-and-off headaches. Did x-rays & blood work. ESR high but TAB negative. Other possibilities besides GC Arteritis?

Have on-and-off headaches.  Did x-rays & blood work.  ESR high but TAB negative.  Other possibilities besides GC Arteritis?

Rare to be GCA: To be honest, it's incredibly rare for a patient under 50 to have GCA. It's really a disease of the elderly. And there is a phenomenon known as biopsy negative GCA, but in a 50 year old I would look elsewhere. It could be many types of headache but you don't provide much of a description. An elevated ESR is nonspecific. Have you seen a neurologist or headache specialist. ...Read more

Is the dna, sda chlamydia test unreliable? It showed me as a negative but i cmae up positive in the rna, tma test. How come?

Is the dna, sda chlamydia test unreliable? It showed me as a negative but i cmae up positive in the rna, tma test. How come?

Generally reliable: Both tests have very high sensitivity and specificity; however, the dna sda test can have false negatives if there is an inhibitor present, such as a high white count in the urine or blood. The rna/tma test is less subject to this, and due to the positive screen and risk/benefit ratio, i would recommend treatment. ...Read more

Received oral sex. Tested 2 wks after. Chlamydia, GC and ngu neg. returned 1.5 wks later reswabed. 7wbc. Told have slight ngu. Never discharge. Ngu?

Maybe nothing wrong: Oral sex is low risk for all STDsIf "never discharge", why were you retested a second time? Any other symptoms? Entirely healthy men have a few WBC from time to time, i.e. maybe nothing wrong. In any case, for sure you don't have gonorrhea or chlamydia. If you're not in the care of one of UK's excellent NHS GUM clinics, consider doing it now. Good luck. ...Read more

How long are specimens good for additional reliable testing? Doctor ordered chlamydia/gc test and 6days later ordered a trich test using same specimen

Preservatives: The lab doing the testing would let your dr. Know if the specimen was outdated. Often, preservatives can be introduced in the specimen as well, making it viable for future testing. If the lab did not have a problem with adding the test, than all is fine. ...Read more
