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 mean corpuscular volume (MCV) - the size of the red blood cells. CBC also includes information about the red blood cells that is calculated from the other measurements: MCH (mean corpuscular hemoglobin; MCHC (mean corpuscular hemoglobin concentration.
The platelet count is also usually included in the CBC.

|
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 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).

Barium enema is a special x-ray of the large intestine, which includes the colon and rectum. Before x-rays are taken, a liquid called barium sulfate is placed in the rectum. The liquid is a type of contrast. Contrast highlights specific areas in the body, creating a clearer image. The barium eventually passes out of the body with the stools.
|
|
A barium enema, also known as a lower GI (gastrointestinal) exam, is a diagnostic test using x-ray examination to view the large intestine (colon and rectum). There are two types of this test: the single-contrast technique, in which barium sulfate solution is injected into the rectum to gain a profile view of the large intestine; and the double-contrast (or air contrast) technique, in which air and barium sulfate are injected into the rectum.

ESR stands for erythrocyte sedimentation rate. It is a nonspecific screening test that indirectly measures how much inflammation is in the body.
|
|
The sedimentation rate test, also called the erythrocyte sedimentation rate (ESR) or sed rate test, measures the speed at which the red blood cells (erythrocytes or RBCs) separate from the liquid part of the blood (plasma) and settle to the bottom in a tube of anticoagulated blood. Purpose The sedimentation rate is a non-specific indicator of the presence of inflammation or infection .
|
|
The erythrocyte sedimentation rate (ESR), or sedimentation rate (sed rate), is a measure of the settling of red blood cells in a tube of blood during one hour. The rate is an indication of inflammation and increases in many diseases.

A fecal occult blood test (FOBT) is a noninvasive test (nothing enters the body. This test detects hidden (occult) blood in the stool. Such blood may come from anywhere along the digestive tract. Hidden blood in stool is often the first, and in many cases the only, warning sign that a person has colorectal disease, including colon cancer.

The fecal occult blood test (FOBT) is performed as part of the routine physical examination during the examination of the rectum. It is used to detect microscopic blood in the stool and is a screening tool for colorectal cancer .

Liver function tests, or LFTs, include tests for bilirubin, a breakdown product of hemoglobin, and ammonia, a protein byproduct that is normally converted into urea by the liver before being excreted by the kidneys. LFTs also commonly include tests to measure levels of several enzymes, which are special proteins that help the body break down and use (metabolize) other substances.
