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).

Carcinoembryonic antigen is a test that measures the amount of carcinoembryonic antigen (CEA) in blood.
|
|
The carcinoembryonic antigen (CEA) test is a laboratory blood study. CEA is a substance which is normally found only during fetal development, but may reappear in adults who develop certain types of cancer .

A colonoscopy is an internal examination of the colon (large intestine), using an instrument called a colonoscope. The colonoscope is a small camera attached to a flexible tube. Unlike sigmoidoscopy, which examines only the lower third of the colon, colonoscopy examines the entire length of the colon.

Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures. With the development of modern computers, the scans enhanced digital capabilities allowed the development of computed tomography imaging (derived from the Greek tomos , meaning " to slice " ).

A fecal occult blood test (FOBT) is a noninvasive test that detects the presence of hidden (occult) blood in the stool. Such blood may arise 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 . There are two types of FOBTs: 1) the traditional guaiac smear test (Hemoccult, Seracult, Coloscreen), and 2) the newer, flushable reagent pads (EZ DetectT, ColoCARE). They are both useful in detecting hidden blood in the stool, and are mainly used for colorectal cancer screening. The tests differ in the way they are performed. The flushable reagent pads are available without a prescription at many drugstores. In contrast, the traditional guaiac smear test is completed and interpreted by a medical professional, and these tests are usually available from a laboratory or a doctor's office. Many consumers prefer the flushable reagent pads because there is no stool handling and no laboratory processing. However, health care providers usually favor the guaiac tests because the large studies that have shown the benefits of colon cancer screening were done with guaiac tests.

A digital rectal exam is an examination of the lower rectum to check for hemorrhoids, anal fissures, and stool abnormalities such as frank (evident) or occult (hidden) blood. The term "digital" refers to the clinician's use of a lubricated finger (digit) to conduct the exam. This examination is also used to evaluate the prostate gland in men.

Sigmoidoscopy is an internal examination of the lower large bowel (colon), using an instrument called a sigmoidoscope. The sigmoidoscope is a small camera attached to a flexible tube. It is inserted into the colon to examine the rectum, and the sigmoid and descending portions of the colon.
|
 |
Sigmoidoscopy is a procedure by which a doctor inserts either a short and rigid or slightly longer and flexible fiber-optic tube into the rectum to examine the lower portion of the large intestine (or bowel). Purpose Sigmoidoscopy is used most often in screening for colorectal cancer or to determine the cause of rectal bleeding.
