All Tests

BLOOD TESTS

(Normal value and its importance )

= Dengue Serology = •          NS1 is a glycoprotein that is common to

all dengue serotypes and can be used to detect either primary or secondary infections in the earliest stages.

•          Serology testing for dengue virus-

specific antibodies, types IgG and IgM, can be useful in confirming primary or secondary diagnosis.

= Chikungunya = •          The type of testing performed is typically dictated by the timing and volume of samples available.

Blood test is the only reliable way to

identify chikungunya since the symptoms are similar to much more deadly dengue fever.

•          Common laboratory tests for chikungunya include for instance RT-PCR and serological tests.

•            HIV tests are used to detect the presence of the human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome(AIDS), in serum, saliva, or urine. Such tests may detect antibodies, antigens, or RNA.

•            The CD4 T-cell count is not an HIV test, but rather a procedure where

the number of CD4 T-cells in the blood is determined.

•            A CD4 count does not check for the presence of HIV.

•               It is used to monitor immune system function in HIV-positive people.

•            A normal CD4 count can range from 500 cells/mm3 to 1000 cells/mm3.

•               In HIV-positive people- CD4 count below 200 cells/μL

= HIV -1 & HIV-2 = •            HIV tests are used to detect the presence of the human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome(AIDS), in serum, saliva, or urine. Such tests may detect antibodies, antigens, or RNA.

•            The CD4 T-cell count is not an HIV test, but rather a procedure where

the number of CD4 T-cells in the blood is determined.

•            A CD4 count does not check for the presence of HIV.

•               It is used to monitor immune system function in HIV-positive people.

•            A normal CD4 count can range from 500 cells/mm3 to 1000 cells/mm3.

•               In HIV-positive people- CD4 count below 200 cells/μL
