LAB QUESTIONS

1) group A- has only A antigen
    group B- has only B antigen
    group AB- has both A and B antigen
group O- has neither A or B antigen 
 

2)  Each blood type is also grouped by its Rhesus factor, or Rh factor. Blood is either Rh positive (Rh+) or Rh negative (Rh-). About 85% of Americans have Rh+ blood.

Rhesus refers to another type of antigen, or protein, on the surface of red blood cells. The name Rhesus comes from Rhesus monkeys, in which the protein was discovered.

3)

Hepatitis b

A severe form of viral hepatitis transmitted in infected blood, causing fever, debility, and jaundice

Syphilis

A chronic bacterial disease that is contracted chiefly by infection during sexual intercourse, but also congenitally by infection of a developing fetus

Hepatitis c

A form of viral hepatitis transmitted in infected blood, causing chronic liver disease. it was formerly called non-a, non-b hepatitis

Human immunodeficiency

Human immunodeficiency virus, a retrovirus that causes aids

Htlv

Human t cell lymphotropic virus

5) biopasy- medical test involving sampling cells or tissues for examination 

smear- screening used to detect potentially pre-cancerous or cancerous  cells

fluid tissue- fluid that surrounds the cells if multi-cellular animals

6) 110 lbs

7) Depending on your height, sec and weight, you can give up to 2 pints in an automated blood collection. For example, one donor may be able to donate two units of Red Blood Cells, another may donate on unite of Platelets and one unit of Plasma.

 

8) An anticoagulant is a type of medication that may be used to prevent blood from coagulating or clotting. There may kinds of anticoagulants and they have different ways of acting. The majority of them are medications that are administered to people to prevent blood clotting in certain illness, but sometimes in lab or medical settings an anti-coagulant is used to prevent things like clogging of intravenous lines or of blood clotting in test tubes and syringes. For medical use in people, it’s also important to mention anti-platelet medications, which have a similar purpose to anticoagulants, though the way they work is different.

9) the purpose is to add visual contrast to otherwise transparent objects, so they will be easier to see and study under the microscope.

10)

retic count- blood test that measures how rapidly immature red blood cells called reticulocytes

diff- measures the percentage of each type of white blood cell (WBC) that you have in your blood

ESR- erythrocyte sedimentation rate (ESR) is an easy, inexpensive, nonspecific test that has been used for many years to help detect conditions associated with acute and chronic inflammation, including infections, cancers, and autoimmune diseases.

Hgb-The hemoglobin test may be used to screen for, diagnose, or monitor a number of conditions and diseases that affect red blood cells (RBCs) and/or the amount of hemoglobin in blood. 

Hbs- Hepatitis B tests may be used for a variety of reasons. Some of the tests detect antibodies produced in response to HBV infection; some detect antigens produced by the virus, and others detect viral DNA.

Hct/Crit- The hematocrit may be used to screen for, diagnose, or monitor a number of conditions and diseases that affect the proportion of the blood made up of red blood cells

MCV-The mean corpuscular volume, or "mean cell volume" (MCV), is a measure of the average red blood cell size that is reported as part of a standardcomplete blood count.

MCH-The mean corpuscular hemoglobin, or "mean cell hemoglobin" (MCH), is the average mass of hemoglobin per red blood cell in a sample of blood. It is reported as part of a standard complete blood count

RBC- red blood cell (RBC) count is typically ordered as part of a complete blood count (CBC) and may be used as part of a health checkup to screen for a variety of conditions.

sed rate-Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can reveal inflammatory activity in your body. A sed rate test isn't a stand-alone diagnostic tool, but it may help your doctor diagnose or monitor the progress of an inflammatory disease.

WBC- blood test to measure the number of white blood cells
