I had unprotected oral sex on me I saw no blood I have no sores I am circumsized I have tooken a HIV dna pcr test at 18 days and a 46 also a 4 week and 6 week duo test and a 8 week rapid test am I ok?

I had unprotected oral sex  on me I saw no blood I have no sores I am circumsized I have tooken a HIV dna pcr test at 18 days and a 46 also a 4 week and 6 week duo test and a 8 week rapid test am I ok?

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

Monotest (target values <1.0=negativ). Values: EBV VCA IgG-Ak 39.9; EBV VCA IgM-Ak 1.1; EBNA-1 IgG-Ak 14.7; EBV DNA (PCR) negativ. What does it mean?

Ask who ordered: The test, but in general, they were suspecting EBV infection/Infectious mononucleosis, which looks negative, the final diagnosis is with the doctor who ordered the blood test. Clinical picture is important, finally we treat patients not lab results, good luck ...Read more

I have oral hair leukoplakia and fever, lymphnodes..etc but HIV PCR RNA 5,15 week; HIV ab 8,13,28,33 weeks all neg, am I HIV free?? Ebv is caus?

Could be-: If repeated HIV testing is (-), and oral hairy leukoplakia (OHL) is present, then you don't have HIV. You have another type of viral infection . EBV is certainly a leading diagnosis- there are specific blood tests that can determine if you have an active or past infection. If the OHL is a soft diagnosis, consider other viruses such as Cytomegalovirus (CMV) and Human Herpesvirus-6 (HHV-6). ...Read more

Is there any case/possibility where HIV ANTIBODIES DOESN'T develop at all for life time? I am negative after 11 months.Will PCR DNA detect HIV aft 1yr

Is there any case/possibility where HIV ANTIBODIES DOESN'T develop at all for life time? I am negative after 11 months.Will PCR DNA detect HIV aft 1yr

Yes, if you have HIV: It is very very unlikely that you have HIV if the antibody test is negative 11 months after exposure. You could get HIV nucleic acid test for your peace of mind, if that is negative, you do not have HIV. ...Read more

Why is the HIV DNA PCR test not recommended after 4 weeks of exposure? Would it still be a good measure if used past a 3 month time frame?

Why is the HIV DNA PCR test not recommended after 4 weeks of exposure? Would it still be a good measure if used past a 3 month time frame?

HIV RNA PCR: It is completely diagnostic at four weeks. Who told you otherwise? But it must be combined with one of the newer generation antibody tests in case you happen to have a natural ability to suppress the viral replication. ...Read more

Does DNA PCR test for HIV 1&2 lose sensitivity over time? How accurate can a negative result for DNA PCR be on checking at 89 days post exposure?

Does DNA PCR test for HIV 1&2 lose sensitivity over time? How accurate can a negative result for DNA PCR be on checking at 89 days post exposure?

No sensitivity loss: These tests do not lose sensitivty over time. A negative result at almost 3 months is almost 100% conclusive. However, to reach 100% certainty, you also need an antibody test, if not already done. ...Read more

Elevated EBV ab VCA IgG <8 and EBV nucleaer antigen ab IgG test 4.2. & anti-dna(ss)igg ab qn ( 119)& c react protien(5.6) what are implications?

Elevated EBV ab VCA IgG <8 and EBV nucleaer antigen  ab IgG test 4.2. & anti-dna(ss)igg ab qn ( 119)& c react protien(5.6)  what are implications?

Nothing.: Ebv antibodies indicate you had a previous infection, but not active. The c-reactive protein needs a units indicator - that is either normal or somewhat elevated. The anti ss dna is extremely nonspecific and very rarely indicated; I have no idea why that was ordered, discuss with your doctor. ...Read more

Is HIV PCR DNA test after 9 weeks conclusive enough?

HIV PCR testing: Yes. This excellent new way of testing viruses is very sensitive. It is thought that the HIV pcr dna test can narrow the window to 14 to 21 days post exposure. A negative test at 9 weeks post exposure means you do not have hiv. ...Read more

How many types of HIV are there?I did HIV DNA PCR for HIV 1 only I'm afraid If I'm infected by other types.

How many types of HIV are there?I did HIV DNA PCR for HIV 1 only I'm afraid If I'm infected by other types.

HIV risks: There are two major strains of HIV in the world - HIV-1 and HIV-2. Almost all infections are HIV-1 unless you live in W. Africa where there is some HIV-2. If your test was negative then that is great. You should still be careful though because HIV infection requires life long medication to manage it. Probably best to get follow up with your doc. There are lots of ways to have safe sex-b careful ...Read more

Is it possible to still carry chlamadyia infection despite a negative result in PCR Dna test??(symptoms persist)

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

HSV 1+2 Serum test resut- 1.77 & HSV Type 1+2 PCR DNA result Negative. Can't understand the difference between two results.

HSV 1+2 Serum test resut- 1.77 & HSV Type 1+2 PCR DNA result Negative. Can't understand the difference between two results.

Need details: PCR will detect herpes virus if present on the skin. If no virus is shedding at the time, then it shows negative. But herpes is present in a dormant form in a nerve and is detected by noting serum antibodies. Antibodies are specific immunity which contain the virus but fail to reach inside a nerve. When the virus sometimes comes out onto the skin it can be detected by PCR. When the virus is only i ...Read more

Epstein Barr Virus (Definition)

The epstein–barr virus (ebv) is a virus in the herpesvirus family and is one of the most common viruses in humans. Ebv is best known as the cause of infectious mononucleosis, and infection with ebv occurs by the oral transfer of saliva and/or genital secretions, hence the moniker "the kissing disease". In the us, about 90 to 95 percent of all adults have ...Read more
