These are tests for hemolysis (red blood cell destruction. There are specific tests which identify the specific types of hemolytic anemia. They are performed after hemolysis has been established. Elevated indirect bilirubin levels; Low serum hapto...

Red blood cells (erythrocytes) transport oxygen and carbon dioxide in the bloodstream, maintain a normal acid-base balance, and determine how thick or thin the blood is. Hemolytic anemia refers to the premature, increased destruction of erythrocyt...

In order to differentiate hemolytic anemia from others, physicians will examine the blood for the number of young red blood cells, since the number of young cells is increased in hemolytic anemia. The physician will also examine the abdominal area...

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).

|
This is a test that detects the Donath-Landsteiner antibody in serum (the portion of blood without cells), which may be related to paroxysmal cold hemoglobinuria.
|
 |
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.
|
 |
This is a test that measures the amount of iron in the blood.
|
|
Iron tests consist of four assays performed on serum or plasma to aid in the diagnosis and treatment of iron deficiency or iron overload. These tests are serum iron, total iron binding capacity (TIBC), serum ferritin, and serum transferrin.
|
|
Iron tests are a group of blood tests that are done to evaluate the iron level in blood serum, the body ' s capacity to absorb iron, and the amount of iron actually stored in the body. Iron is an essential trace element; it is necessary for the formation of red blood cells and certain enzymes.
|
|
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 blood test provides information about the number and shape of blood cells by visual inspection.
|
|
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 test roughly measures the various types of protein in the serum portion of a blood sample. See also immunoelectrophoresis - serum ; immunofixation - serum ; serum globulin electrophoresis .
|
 |
Electrophoresis is a technique used to separate the different components (fractions) of a mixture, such as proteins in a biological sample. Separation is based on differences in the charge (and sometimes size) of the molecules, which determines their rate of movement in an electric field.
|
|
Electrophoresis is a technique used to separate different elements (fractions) of a blood sample into individual components. Serum protein electrophoresis (SPEP) is a screening test that measures the major blood proteins by separating them into five distinct fractions: albumin, alpha 1 , alpha 2 , beta, and gamma proteins.
|
|
|
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.
|
 |
This is a test that measures the percentage of reticulocytes (slightly immature red blood cells) in blood.
|
|
A reticulocyte count is a blood test performed to assess the body ' s production of immature red blood cells (reticulocytes). A reticulocyte count is usually performed when patients are evaluated for anemia and response to its treatment.
|
|
|
This test measures the amount of potassium in the blood.
|
 |
A urine albumin test measures the amount of protein in urine.
