The following is a list of AIDS-related infections and cancers that people with AIDS may get as their CD4 count decreases. In the past, having AIDS was defined as having HIV infection and getting one of these additional diseases. Today, according ...

Because HIV infection produces such a wide range of symptoms, the CDC has drawn up a list of 34 conditions regarded as defining AIDS. The physician will use the CDC list to decide whether the patient falls into one of these three groups: definitiv...

In the early stages of infection, HIV often causes no symptoms and the infection can be diagnosed only by testing a person's blood. Two tests are available to diagnose HIV infection, one that looks for the presence of antibodies produced by the bo...

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

ELISA stands for enzyme-linked immunoassay. It is a commonly used laboratory test to detect antibodies in the blood.

HIV ELISA/Western blot is a set of blood tests used to diagnose chronic infection with human immunodeficiency virus (HIV.

AIDS tests, short for acquired immunodeficiency syndrome tests, cover a number of different procedures used in the diagnosis and treatment of HIV patients. These tests are sometimes called AIDS serology tests. Serology is the branch of immunology that deals with the contents and characteristics of blood serum. Serum is the clear light yellow part of blood that remains liquid when blood cells form a clot. AIDS serology evaluates the presence of human immunodeficiency virus (HIV) infection in blood serum and its effects on each patient's immune system.

AIDS tests, short for acquired immunodeficiency syndrome tests, cover a number of different procedures used in the diagnosis and treatment of HIV-infected patients. Tests that measure antibodies to the human immunodeficiency virus (HIV) are called AIDS serology tests. Serology is the branch of immunology that deals with the identification and measurement of antibodies in serum which indicate the presence of disease or immunity to disease. Serum is the normally clear light yellow noncellular portion of blood that forms after the sample is allowed to clot. Some AIDS tests measure HIV antigens or nucleic acid rather than antibodies produced in response to HIV infection . AIDS tests evaluate the presence of HIV in blood serum, and the effects of HIV infection on the patient's immune system .

The blot test is a method used to detect and identify DNA or RNA samples, using absorbent paper electrophoresis. The original test in this group was developed by British biologist M. E. Southern in 1975, and is named the Southern blot test. As related tests using the same general method were developed, they were named for the points of the compass. The Western blot test is a specific test that uses paper electrophoresis to detect HIV (human immunodeficiency virus), and it is widely used in screening for HIV infection. J OHN M.

T cells are a type of white blood cells (lymphocytes. They make up part of the immune system. T cells help the body fight diseases or harmful substances. A test can be done to measure the number of T cells in your blood.

A complete blood count (CBC) test measures the following: The number of red blood cells (RBCs; The number of white blood cells (WBCs; The total amount of hemoglobin in the blood; The fraction of the blood composed of red blood cells (hematocrit; The size of the red blood cells (mean corpuscular volume, or MCV. The CBC test also provides specific information the size and hemoglobin content of individual red blood cells. This is determined from the additional following measurements: Mean corpuscular hemoglobin (MCH; Mean corpuscular hemoglobin concentration (MCHC. The platelet count is also usually included in the CBC. See also: Red blood cell (RBC) count; White blood cell (WBC) count.

One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (plasma). It involves determining the numbers, concentrations, and conditions of the different types of blood cells.

A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet count; measurement of hemoglobin and mean red cell volume; classification of white blood cells (WBC differential); and calculation of hematocrit and red blood cell indices . The hematocrit is the percentage of blood by volume that is occupied by the red cells (i.e., the packed red cell volume). Red blood cell indices are calculations derived from the red blood cell count, hemoglobin and hematocrit that aid in the diagnosis and classification of anemia.

The clinical laboratory test that evaluates the three main cellular components of peripheral blood (red cells, white cells, and platelets) is called the "complete blood count" (CBC). It is used commonly to assess whether a patient is anemic (low red cell count), has an infection (increased white blood cells), or has abnormal blood coagulation (platelet levels). The CBC examines the total number of red blood cells (RBC) and the RBC indices, including: the mean corpuscular volume (MCV); the concentration of hemoglobin, measured by the mean corpuscular hemoglobin (MCH) and its concentration (MCHC); and the hematocrit, which is the mean packed-cell volume of red cells. The total white blood cell (leukocyte) count, the various types of leukocytes (lymphocytes, monocytes, neutrophils, eosinophils, and basophils), and platelets are also measured. J ONATHAN R.
