Is A Negative ELISA Test After 40 Days Of Exposure Conclusive?
PCR quite effective for detection of chlamydiae and neisseria
Hi Mr XXXXXXX
Welcome to health care magic,
Based on the details and reports in your query, you have been screened for STDs (Sexually transmitted infections/diseases) and you are negative for all.
Chlamydia are cell wall deficient forms which do not grow so easily in routine culture media and grow only in special cell cultures. Neisseria species also need special media to isolate them like chocolate agar and Stuarts media.Hence PCR is preferred to diagnose these infections.
Moreover, you mention that you had protected sex which makes you most unlikely to have acquired any infection.
Your urine culture report indicates that you do not suffer from urinary tract infection caused by aerobic pyogenic bacteria.
Now, coming to your symptoms, I am suspecting ureteric colic which is commonly caused by the obstruction of the urinary tract by calculi or stones.
The classic presentation of a ureteric colic is acute, colicky flank pain radiating to the groin. I suggest you get a urologist opinion for the same.
I can assure you that you do not suffer from any sexually transmitted infection.
I hope I was able to clear your doubts satisfactorily,
Please get back if any more queries.
No need to worry. HIV testing for antibodies done after 3 months
Hi Mr XXXXXXX
I understand your anxiety regarding exposure to STDs especially HIV.
But as you have had an encounter which was protected, most unlikely chance of any infection to have occurred.
Moreover, tests for HIV antibodies can be done only after three weeks of exposure because antibodies against HIV are produced only then.
You have undergone ECLIA for HIV twice at 40th day and 60th day and both the results are negative. According to NACO guidelines if two test results for HIV are negative, HIV status is negative.
The three months period you are talking about in your query is called the window period where some individuals may give negative results for antibodies against HIV.
To rule out this period, many get a confirmatory test done after 100 days of exposure to confirm the negative status.
If you are very anxious, you can get a repeat test done on 100th day for HIV 1 and 2 antibodies.
Mind you, this test will be only be to confirm your negative status, so please do not worry unnecessarily.
I hope I have helped you with my answers.
Please get back if any more doubts.
