Question 1

hi, can taking antibiotics cause false negative results in hiv elisa test?

Accepted Answer

Unlikely: Antibiotics should not affect the saliva test results.
If you have any concerns, get a blood test for HIV nucleic acid.

Question 2

what reasons would cause an hiv dna/pcr test to be "false negative". does waiting too long to test using it effect the result?

Accepted Answer

False Negative: A  false negative means that a test result said a condition was not present when it was, thus the negative result is false.  Please let your doc determine what is false negative or false positive.  Peace and good health.

Question 3

is there any disease (including stds) that can cause false negative to hiv tests (cmia & elisa) or affect hiv test results?

Accepted Answer

: No, none. With the HIV tests in nearly universal use in recent years, including CMIA and ELISA, there are no medical conditions or medications of any kind that interfere with the reliability of the results.

Question 4

would clobetasol propionate (dermovate 500mcg/g ointment) cause false negative test result to syphilis and hiv if applied on open wounds?

Accepted Answer

No: This will not affect any blood test results.

Question 5

Results real: Regardless of technique, the results should be accurate. Good luck

Question 6

can a autoimmune disease cause false negative hiv test with 4th generation at 24 weeks ? and can tinea versicolor affect the results or no?

Accepted Answer

: Autoimmune disorders are known to cause false positive HIV tests. I'm unsure whether tinea versicolor can, but this fungus infection certainly can occur in hiv patients.

Question 7

Accepted Answer

HIV Testing: Typically, most people who acquire the infection have a measurable antibody titer by three months after exposure. If you were negative at 8 months, it is vanishingly unlikely that you had a false negative test result.

Question 8
