Question

Western blot test is used for confirmation of
A. Filaria
B. Anaemia
C. Malaria
D. AIDS

Answer 1

Hint: During western blot test a small amount of blood sample is taken and it is used to detect HIV. In this test, it separated the blood proteins and detected specific HIV antibodies which indicated an HIV infection. The western blot test is used to confirm positive ELISA, and combined tests are 99.9% accurate.

Complete answer:
Western blot test is used in the detection of HIV in serum, saliva or urine. In this test HIV proteins are placed within the slab of gel on a membrane patient's serum is applied to the membrane and the antibodies present in the serum get attached to HIV proteins. Antibodies which do not get detached are discarded and enzyme linked antibodies with capabilities to attach to the person antibodies determine the HIV proteins on which the antibodies are bound. These attached antibodies are then studied and which determines the result of HIV which is associated with AIDS.
Complete Blood Count is used to count the number of blood tests in the blood sample to determine anaemia. Then a test is conducted to determine the shape and size of the blood cells. Filaria is determined by the identification of microfilariae in the blood smear by the help of a microscope. Blood smear study under the microscope is helpful to determine malaria in the body.

Note:
 HIV infection leads to the disease AIDS if left untreated. AIDS is the late stage of HIV which occurs when the immune system is badly damaged because of the virus.
