Diagnosis of HIV
Diagnosis of HIV is not easy. There are no symptoms of HIV but it is through the infection of other diseases that HIV is detected. The characterists of HIV and its unnoticed invasion and growth in the CD4 cell makes it very difficult to diagnose HIV. There are some tests available to detect HIV, while some does not work, others detect HIV at a very late stage. When it comes diagnosis of HIV one thing to remeber is that the HIV is not detected by the body at any time of its life cycle, so the body does not make any antibody against HIV. So if a medicine claims that it will detect the antibodies of HIV, as do all the over the counter test kits and do it at home test kits, then are taking you for a ride.
Diagnosis of HIV
A complete blood check up would be the most important test for persons who are suspected to have HIV infection.
If there are noticible changes in the CD4 cells then tests will be recommended like the antibody test or antibody and antigen detection test or the Nucleic Acid Test.
Among these only the antigen detection test and Nucleic Acid test are able to detect the presence of HIV that too at a very late stage. But all these test can detect AIDS diseases.
The antibody tests for HIV itself claims that the test can make a HIV positive person to be negetive and can present the report for normal person as HIV positive. And then they give the excuse of window period. After the window period it will treat the antibody for many diseases to be as antibody of HIV. Unaware of the fact that HIV is never detected by the body all through the lifecycle of HIV and hence no antibody is made by the body to protect the body from HIV.
Among the antibody tests that cannot prove the presence of HIV are the ELISA test, Home access express tests, Saliva tests, western blot and many others.
Other than the tests the doctor will also look into the medical history of the person, regarding the diseases the person is suffering from or was suffering from.
The doctor may ask as to why the person feels that he / she may have infected with HIV. If the narrative of the person states that the person believes he / she was infected by one of the causes of HIV infection then the doctor will continue with regard to the infective capacity of the situation that the person had undergone.
A physical examination is also done to inspect the condition of the body and its physical strength.
Family history for HIV infection or HIV infections in the peer group. Access of the person to HIV infected person.
The doctor may also check for symptoms of AIDS category diseases, because AIDS category diseases show their symptoms very clearly.
The factors that facilitate the diagnosis of the HIV includes.
Reduction in the CD4 count of the person.
The Antigen and Nucleic tests coming out positive.
Patients narrative proves that an infection is possible.
Person having family history of HIV infection.
Person suffering from many diseases indicating weak immune system.
Person showing symptoms of AIDS category disease.
It is not unusual if the person notices that the doctor may be as confused as the person because a systematic and comprehensive method of testing for HIV is still not available. Despite the development of various methods of treatments that can prolong the life of the HIV positive with drugs and medication, the diagnosis of HIV is still made on guess work. With the positive tests turning negative and negative tests turning positive, it is only after a continous testing and reptitative followups and the body condition of the person that the doctor can guess that the person may be infected with HIV. The response given by the body of the person to various drugs and medications of HIV, is also used to diagnose the presence of HIV infection.
