The health care provider will perform a physical exam. Tests that may be done include: Bone marrow biopsy; Blood volume; Chemistry panel; Complete blood count with differential; Hematocrit; White blood count; Platelet count; Vitamin B12 level. Thi...

PV is often a diagnosis of exclusion, which means that the doctor will first rule out other possible causes of the patient's symptoms. The doctor can detect some signs of the disorder during a physical examination. Patients with PV will have an en...

Bone marrow is soft tissue found inside some of the larger bones in the body. The marrow produces platelets and red and white blood cells. A biopsy is a method of removing a small tissue sample from the body to have it examined under a microscope and possibly analyzed by other tests.

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.
|
 |
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).

ESR (erythrocyte sedimentation rate) is a nonspecific screening test for various diseases. This 1-hour test measures the distance (in millimeters) that red blood cells settle in unclotted blood toward the bottom of a specially marked test tube.
|
|
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.
|
 |
The hematocrit is the percent of whole blood that is composed of red blood cells. The hematocrit is a measure of both the number of red blood cells and the size of red blood cells. The hematocrit is almost always ordered as part of a complete blood count , which measures the number of red blood cells, the number of white blood cells, the total amount of hemoglobin in the blood, and the fraction of the blood composed of red blood cells (hematocrit).
|
|
Blood has a liquid component (plasma) and a particulate component (blood cells). The denser blood cells (most of which are red blood cells) will settle in a tube, particularly if the blood is spun in a device called a centrifuge.
|
|
The hematocrit measures how much space in the blood is occupied by red blood cells. It is useful when evaluating a person for anemia.
|
|
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)

Lactate dehydrogenase, also called lactic dehydrogenase, or LDH, is an enzyme found in the cells of many body tissues, including the heart, liver, kidneys, skeletal muscle, brain, red blood cells, and lungs. It is responsible for converting muscle lactic acid into pyruvic acid, an essential step in producing cellular energy.
|
|
This is a test that measures the amount of an enzyme called alkaline phosphatase within white blood cells (leukocytes).
|
|
This is a test of the ability of platelets , a component of blood, to clump together and cause blood clotting.
|
|
Platelets (thrombocytes) are small anucleate (i.e.
|
|
Platelets are disk-shaped blood cells that are also called thrombocytes. They play a major role in the blood-clotting process.
|
|
This is a test to measure the number of platelets in blood. Platelets are a type of blood cell. They play a key role in normal blood clotting. During the clotting process, platelets clump together to plug small holes in damaged blood vessels. The purpose of clotting is to stop bleeding. Platelets also activate factor VIII and release phospholipids as part of the blood clotting process.
|
|
A platelet count is a diagnostic test that determines the number of platelets in the patient ' s blood. Platelets, which are also called thrombocytes, are small disk-shaped blood cells produced in the bone marrow and involved in the process of blood clotting.
|
 |
This is a blood test that measures the number of red blood cells (RBCs). The RBC count is almost always part of the CBC (complete blood count) test. RBCs transport hemoglobin . Hemoglobin transports oxygen. The amount of oxygen body tissues receive depends on the amount and function of RBCs and hemoglobin. RBCs normally survive about 120 days in the blood. They are then removed by specialized "clean-up" cells in the spleen and liver.
|
 |
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.
|
 |
This is a test to measure the amount of uric acid in the blood.
|
|
The vitamin B-12 level is a test to determine the level of vitamin B-12 in the blood.
|
 |
Urinalysis is a physical and/or chemical examination of the urine. It consist of a battery of chemical and microscopic tests to screen for urinary tract infections , renal (kidney) disease , and diseases of other organs that result in the appearance of abnormal metabolites (break-down products) in the urine.
|
|
Urinalysis is a diagnostic physical, chemical, and microscopic examination of a urine sample (specimen). Specimens can be obtained by normal emptying of the bladder (voiding) or by a hospital procedure called catheterization.
|
|
The urine specimen collection is a procedure used to obtain a sample of urine from a patient for diagnostic tests. Purpose The purpose of obtaining a urine sample is to test for any abnormalities that may be present, such as bacteria , ketones, or drugs.
|
|
A urinalysis is a group of manual and/or automated qualitative and semi-quantitative tests performed on a urine sample. A routine urinalysis usually includes the following tests: color, transparency, specific gravity, pH, protein, glucose, ketones, blood, bilirubin, nitrite, urobilinogen, and leukocyte esterase.

|
Urinalysis is an important test used in diagnosing diseases of the genitourinary tract. Urine is examined for pH and specific gravity by chemical and direct microscopic methods.
|
|
Urine typically contains epithelial cells shed from the urinary tract. Urine cytology evaluates this urinary sediment for the presence of cancerous cells from the lining of the urinary tract, and it is a convenient noninvasive technique for follow-up analysis of patients treated for urinary tract cancers.
|
|
A urine dipstick is a colorimetric chemical assay that can be used to determine the pH, specific gravity, protein, glucose, ketone, bilirubin, urobilinogen, blood, leukocyte, and nitrite levels of an individual ' s urine. It consists of a reagent stick-pad, which is immersed in a fresh urine specimen and then withdrawn.
|
 |
This is a blood test to measure the number of white blood cells (WBCs). It is almost always part of the CBC (complete blood count). See also blood differential .
|
 |
A white blood cell (WBC) count determines the concentration of white blood cells in the patient ' s blood. A differential determines the percentage of each of the five types of mature white blood cells.
