You're OK: Oral sex is safe sex for HIV, with no proved transmissions by fellatio from mouth to penis, only rare ones penis to oral. You didn't need testing on account of this event and for sure not the multiple expensive ones you had. But the results from that combination of tests are conclusive. For sure you didn't catch HIV during that exposure and no further testing is needed. Best wishes and stay safe! ...Read more

Polymerase Chain Reaction (Definition)

Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more

What is the definition or description of: pertussis in nasal swab (pcr test)?

What is the definition or description of: pertussis in nasal swab (pcr test)?

Pertussis was foun: It means that they found evidence that the bacteria that causes whooping cough was present in the nasal passages. This could mean you are a carrier of the disease (could infect others) or if you are having symptoms or repeated, serious cough, then you likely got infected by the pertussis bacteria and have whooping cough. ...Read more

What is the definition or description of: pertussis found on nasal swab (dfa)?

What is the definition or description of: pertussis found on nasal swab (dfa)?

Rapid screening test: Dfa--direct fluorescent antibody test--a rapid diagnostic test done in the lab that takes 1-2 days to screen for pertussis (whooping cough). While much faster than a culture, this test is not as reliable. A nasal swab is inserted gently into the nostrils toward the throat (posterior nasopharynx). Then fluorescently labeled antibodies are exposed to the sample looking for pertussis antigens/markers. ...Read more

What exactly a polymerase chain reaction is or a "pcr test?

Nucleic acid testing: Pcr allows enormous expansion of a chosen, limited segment of dna and facilitate testing of nucelic acid abnormalties. Pcr by itself is not a test. The specificity of the test is detemined by the composition of the probes used to analyse the nucelic acids. ...Read more
