Blood Cell Count

Blood Cell Count

A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia.

A complete blood count test measures several components and features of your blood, including:

Red blood cells, which carry oxygen
White blood cells, which fight infection
Hemoglobin, the oxygen-carrying protein in red blood cells
Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in your blood
Platelets, which help with blood clotting

Abnormal increases or decreases in cell counts as revealed in a complete blood count may indicate that you have an underlying medical condition that calls for further evaluation.

Why it's done

A complete blood count is a common blood test that's done for a variety of reasons:

To review your overall health. Your doctor may recommend a complete blood count as part of a routine medical examination to monitor your general health and to screen for a variety of disorders, such as anemia or leukemia.
To diagnose a medical condition. Your doctor may suggest a complete blood count if you're experiencing weakness, fatigue, fever, inflammation, bruising or bleeding. A complete blood count may help diagnose the cause of these signs and symptoms. If your doctor suspects you have an infection, the test can also help confirm that diagnosis.
To monitor a medical condition. If you've been diagnosed with a blood disorder that affects blood cell counts, your doctor may use complete blood counts to monitor your condition.
To monitor medical treatment. A complete blood count may be used to monitor your health if you're taking medications that may affect blood cell counts.

Hemoglobin

Amount of this oxygen-carrying protein within red blood cells

Men: 14 to 16 grams per deciliter

Women: 12.5 to 15 grams per deciliter

Hematocrit

proportion of red blood cells to the total blood volume

Men: 42 to 50%

Women:38 to 47%

Mean corpuscular volume

Stimate of the volume of red blood cells

86 to 98 cubic micrometers

White Blood Cell Count

Precentages of the different types of white blood cells

segmented neutrophils: 34 to 75%

Band neutrophils: 0 to 8%

Lymphocytes: 12 to 50%

Monocytes: 15%

Eosinophils: 0 to 5%

Basophils: 0 to 3%

Platelet Count:

Number of Platelets in a specified volume of blood.

140,000 to 450,000 per microliter.

Common Diagnostic of Barium X-ray Studies

Common Diagnostic of Barium X-ray Studies a). Body area tested: Esophagus, Stomach, duodenum, intestine. b). Description: X-ray study to detect ulcers, tumors, or other abnormalities. What does a barium swallow test show? A barium swallow is a test that may be used to determine the cause of painfulswallowing, difficulty with swallowing, abdominal pain, bloodstained vomit, or unexplained weight loss. Barium sulfate is a metallic compound that shows up on X-rays and is used to help see abnormalities in the esophagus and stomach. Where is a barium swallow test performed? A barium swallow may be performed separately or as part of an upper gastrointestinal (UGI) series, which evaluates the esophagus, stomach, and duodenum (first part of the small intestine).

Urine Culture

Urine Culture A urine culture is a test that can detect bacteria in your urine. This test can find and identify the germs that cause a urinary tract infection (UTI). Bacteria, which typically cause UTIs, can enter the urinary tract through the urethra. In the environment of your urinary tract, these bacteria can grow rapidly and develop into an infection. Who is the test for? Urine cultures can identify the microorganisms, typically bacteria, which cause a UTI. UTIs are more common in females than males. This is because a woman’s urethra is shorter and much closer to the anus. Therefore, it’s much easier for bacteria from the intestines to find their way into the urinary tract. Bacteria ascend the urethra into the bladder, ureters, and kidneys, where they can develop into an infection. How is the test administered? The urine for a urine culture can be collected in several different ways. The most common method for collecting urine is the midstream cl...

Common Diagnostic Procedure of Blood Tests

Common Diagnostic Procedure of Blood Tests a). Body area tested: Usually blood sample from an arm. b). Measurement of substances in the blood to evaluate organ function and to help diagnose and monitor various disorders. Common Blood Tests; Tests Reference Range Acidity(pH) 7.35-7.45 Acidity and alkalinity are expressed on the pH scale, which ranges from 0 (strongly acidic ) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of 7.35 to 7.45. Usually the body maintains the pH of blood...
