Q: 

What Are The Laboratory-tests Used In The Treatment Of HIV Infection?

A: There are plenty of laboratory tests for HIV infection. Below are listed few: • Blood Tests (Serology): Initially developed during 1985, the HIV blood tests have developed its arena in quite a significant manner. • Patient nowadays are suggested to go through enzyme-linked immunosorbent assay (ELISA) in order to detect the presence of the antibody in their blood. ELISA results are then analysed through Western Blot Test for further confirmation. It has been observed that the combination of ELISA and Western Blot Test can determine the presence of HIV antibody with 99.9% accuracy. • Another blood test includes the polymerase chain reaction (PCR) that is used to identify and analyse the...
Q: 

what are...?

A: There are two broad categories of HIV tests: screening tests and confirmatory tests. Using these two types of test together can lead to highly accurate and reliable diagnosis of HIV infection. Screening tests Screening tests are used for initial testing because they are easier to perform than confirmatory tests, well suited to testing large numbers of samples, and less costly. They are highly sensitive and result in few false negatives (i.e., most infected people test positive). However, screening tests are not as specific as confirmatory tests, so in a small percentage of cases the test result will be positive even if the person is not infected. Therefore, providers should never give results from screening tests that have not been verified through a confirmatory test. ELISA tests The most...
Q: 

Lyme vs. HIV? Weird question

A: Bob: The standard test for HIV is an enzyme-linked immunosorbent assay or ELISA.  This test is used to test for other diseases/conditions, but of course the assay is specific to the disease/condition it is designed for.  Thus, an ELISA for HIV would *NOT* pick up any other disease, even though the same "type" of test may be used to detect both. I hope this is clear. David...


Q: 

Concerned about initial CMV infection at early pregnancy

A: Cytomegalovirus, or CMV, is found universally throughout all geographic locations and socioeconomic groups, and infects between 50% and 85% of adults in the United States by 40 years of age. CMV is also the virus most frequently transmitted to a developing child before birth. CMV infection is more widespread in developing countries and in areas of lower socioeconomic conditions. For most healthy persons who acquire CMV after birth there are few symptoms and no long-term health consequences. Some persons with symptoms experience a mononucleosis-like syndrome with prolonged fever, and a mild hepatitis. Once a person becomes infected, the virus remains alive, but usually dormant within that person''s body for life. Recurrent disease rarely occurs unless the person''s immune system is...


Q: 

What Is an ELISA Test?

A: An enzyme-linked immunosorbent assay, or ELISA, test is a type of medical diagnostic test used to detect whether a certain antibody or antigen is present in a patient. It can be useful for a range of different purposes relating to immunology, such as disease testing and virus testing. For example, an ELISA HIV test may be administered to determine whether a patient has been infected with HIV antibodies. In addition, ELISA tests are sometimes also used in testing for illegal drug use. An ELISA test can also help detect allergic reactions to food products like nuts or dairy items. During an ELISA procedure, a health care provider typically collects a blood sample from a patient. This is...
Q: 

What is an ELISA HIV Test?

A: ELISA is an acronym for enzyme-linked immunosorbant assay. The ELISA HIV test is just one of the types of ELISA tests widely used in the scientific community. The ELISA HIV test was one of the original diagnostic tools used for HIV and AIDS. An ELISA test is a test used to determine if there are antibodies or antigens in the body. When conducting an ELISA HIV test, a special slide is prepared that contains HIV antigens. Serum from the person receiving the test is applied to the slide. If the person is HIV positive, their body fluids will contain antibodies for the illness. These antibodies will bind to the antigens. After this process, the slide is washed in a solution that removes everything except the antigen and...
Q: 

What is the differnce between SPOT test and ELISA test ? please advice.?

A: Spot tests are usually rapid, with results in minutes to hours, so are used for screening purposes. A positive result tells the doctor to do further testing. ELISA is an abbreviation for "enzyme-linked immunosorbent assay." It is a more involved test, so takes much longer to get results. And the results are generally much more accurate than what you'd get with a spot test. "An ELISA test uses components of the immune system and chemicals to detect immune responses in the body (for example, to infectious microbes). The ELISA test involves an enzyme (a protein that catalyzes a biochemical reaction). It also involves an antibody or antigen...
Q: 

How To Screen for Hepatitis C

A: Hepatitis C is a disease affecting the liver. It is caused by a virus (the Hepatitis C virus, or HCV). This is considered to be the most serious type of hepatitis, and it is also the most common blood-borne pathogen. Hepatitis C causes chronic liver disease, which will then lead on to further complications, such as total liver failure. This disease leads to about 8,000 to 10,000 deaths per year in the United States alone. Apart from fatigue, muscle ache, fever and loss of appetite, Hepatitis C usually has no discernible symptoms at its onset. That’s why it’s very important that a person suspected of having this disease be screened at once, to give him the possibility of early intervention. Here are the ways to screen a person for Hepatitis C:  Know the people at risk for infection. Do...


Q: 

How do you manage chikungunya in infants?

A: Dear Ms. I can take no credit for this, other than to know how to ''cut & paste'' This is from the WHO (World Health Organization) web site. Your question was posted on Dc 26th. I hope and pray that the child found treatment for his/her symptoms. Link: WHO, Chikungunya Key facts •Chikungunya is a viral disease that is spread by mosquitoes. It causes fever and severe joint pain. Other symptoms include muscle pain, headache, nausea, fatigue and rash. •The disease shares some clinical signs with dengue, and can be misdiagnosed in areas where dengue is common. •There is no cure for the disease. Treatment is focused on relieving the symptoms. •The proximity of mosquito breeding sites to human habitation is a significant risk factor for chikungunya. •The disease occurs in Africa, Asia and the...


Q: 

How long does it take to get Results of testing for HIVAIDS?

A: The PCR Test (Polymerase Chain Reaction) test can yield results in as little as 2-3 weeks after infection. PCR testing is not often offerred to adults as it''s complex and costly to perform, but if you''re willing to pick up the tab, you can get one, and they''re faster. The HIV Antibody Test (or ELISA test, for enzyme-linked immunosorbent assay) is more frequently performed. The results usually take 8-12 weeks, and in very rare instances, can require up to 18 months to yield results. Taking the ELISA test before three months after exposure may not provide enough time for antibodies to form, so results will either be positive or inconclusive. This 3-month span is called the Window Period,...
