Donor Testing

RDS Infusions performs these tests for potential donors:

Stool: O&P, C&S, C-Diff

Blood: HIV, Hep B Surface Antigen, Hep C Antibody, CBC, CMP, Hepatitis A Antibody

Stool:

1. O&P x3:

Also known as: Ova and Parasites Exam:

This test identifies the presence of disease-causing bacteria in the stool.

 2. C&S:

Also known as: Bacterial Culture, stool; Feces Culture

A stool culture is used to detect the presence of disease-causing bacteria (pathogenic) and help diagnose an infection of the digestive tract.

3. C-Diff :

Also known as: C. difficile

The stool C. difficile toxin test detects harmful substances produced by the bacterium Clostridium difficile (C. difficile) in a stool sample.

Blood:

1. HIV PCR:

HIV tests are used to detect the presence of the human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS). The HIV PCR test is one the most accurate diagnostic tools in use to detect the presence of the human immunodeficiency virus in the blood, more commonly known as HIV. Aside from being considered more reliable in terms of accuracy than most other tests, the HIV PCR test is also one of the few screening procedures that can be used for early detection. Most people can get an accurate test reading three to four weeks after a suspected infection

2. Hep B Surface Antigen:

Used to screen for and detect HBV infections; earliest indicator of acute hepatitis B and frequently identifies infected people before symptoms appear.

3. Hep C Antibody:

Test for determining whether you have been infected with hepatitis C. The results will come back as either positive or negative

4. CBC:

Also known as a Complete Blood Count

A CBC test usually includes:

  • White blood cell (WBC, leukocyte) count. White blood cells protect the body against infection. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it. White blood cells are bigger than red blood cells but fewer in number. When a person has a bacterial infection, the number of white cells rises very quickly. The number of white blood cells is sometimes used to find an infection or to see how the body is dealing with cancer treatment.
  • White blood cell types (WBC differential). The major types of white blood cells are neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Immature neutrophils, called band neutrophils, are also part of this test. Each type of cell plays a different role in protecting the body. The numbers of each one of these types of white blood cells give important information about the immune system. Too many or too few of the different types of white blood cells can help find an infection, an allergic or toxic reaction to medicines or chemicals, and many conditions, such as leukemia.
  • Red blood cell (RBC) count. Red blood cells carry oxygen from the lungs to the rest of the body. They also carry carbon dioxide back to the lungs so it can be exhaled. If the RBC count is low (anemia), the body may not be getting the oxygen it needs. If the count is too high (a condition called polycythemia), there is a chance that the red blood cells will clump together and block tiny blood vessels (capillaries). This also makes it hard for your red blood cells to carry oxygen.
  • Hematocrit (HCT, packed cell volume, PCV). This test measures the amount of space (volume) red blood cells take up in the blood. The value is given as a percentage of red blood cells in a volume of blood. For example, a hematocrit of 38 means that 38% of the blood’s volume is made of red blood cells. Hematocrit and hemoglobin values are the two major tests that show if anemia or polycythemia is present.
  • Hemoglobin (Hgb). The hemoglobin molecule fills up the red blood cells. It carries oxygen and gives the blood cell its red color. The hemoglobin test measures the amount of hemoglobin in blood and is a good measure of the blood’s ability to carry oxygen throughout the body.
  • Red blood cell indices. There are three red blood cell indices: mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). They are measured by a machine and their values come from other measurements in a CBC. The MCV shows the size of the red blood cells. The MCH value is the amount of hemoglobin in an average red blood cell. The MCHC measures the concentration of hemoglobin in an average red blood cell. These numbers help in the diagnosis of different types of anemia. Red cell distribution width (RDW) can also be measured which shows if the cells are all the same or different sizes or shapes.
  • Platelet (thrombocyte) count. Platelets (thrombocytes) are the smallest type of blood cell. They are important in blood clotting. When bleeding occurs, the platelets swell, clump together, and form a sticky plug that helps stop the bleeding. If there are too few platelets, uncontrolled bleeding may be a problem. If there are too many platelets, there is a chance of a blood clot forming in a blood vessel. Also, platelets may be involved in hardening of the arteries (atherosclerosis).
  • Mean platelet volume (MPV). Mean platelet volume measures the average amount (volume) of platelets. Mean platelet volume is used along with platelet count to diagnose some diseases. If the platelet count is normal, the mean platelet volume can still be too high or too low.

5. Hepatitis A Antibody

This test is a blood test that looks for proteins (antibodies) made by the body in response to the virus that causes hepatitis A. These proteins will be present in your blood if you have a hepatitis A infection now or have had one in the past. It is important to identify the type of hepatitis virus causing the infection to prevent it from spreading and to start the proper treatment.

6.CMP:

Also known as Comprehensive Metabolic Panel

This is a blood test that provides information about: how the kidney and liver are functioning sugar (glucose) and protein levels in the blood the body’s electrolyte and fluid balance

The CMP helps evaluate:

Glucose, a type of sugar used by the body for energy. Abnormal levels can indicate diabetes or hypoglycemia (low blood sugar).

Calcium, which plays an important role in muscle contraction, transmitting messages through the nerves, and the release of hormones. Elevated or decreased calcium levels may indicate a hormone imbalance or problems with the kidneys, bones, or pancreas.

Albumin and total blood protein, which are needed to build and maintain muscles, bones, blood, and organ tissue. The CMP measures albumin specifically (the major blood protein produced by the liver), as well as the amount of all proteins in the blood. Low levels may indicate liver or kidney disease or nutritional problems.

Sodium, potassium, carbon dioxide, and chloride (electrolytes), which help regulate the body’s fluid levels and its acid-base balance. They also play a role in regulating heart rhythm, muscle contraction, and brain function. Abnormal levels also may occur with heart disease, kidney disease, or dehydration.

Blood urea nitrogen (BUN) and creatinine, which are waste products filtered out of the blood by the kidneys. Increased concentrations in the blood may signal a decrease in kidney function.

Alkaline phosphatase (ALP), alanine amino transferase (ALT), aspartate amino transferase (AST), and bilirubin; ALP, ALT, and AST are liver enzymes; bilirubin is produced by the liver. Elevated concentrations may indicate liver dysfunction.
