RBC

Back 1

women 4.2 − 5.4
men 4.7 − 6.1

measures number of RBC's To evaluate the number of circulating red cells in the blood to assist in diagnosing disease and monitor therapeutic treatment. Variations in the number of cells is most often seen in anemias, cancer, and hemorrhage.

Low RBC count leads to anemia. Anemia can be caused by blood loss, decreased blood cell production, increased blood cell destruction, or hemodilution.

High RBC count leads to polycythemia. Polycythemia can be caused by dehydration, decreased oxygen levels in the body, and an overproduction of RBCs by the bone marrow.

women 37% - 47%
men 42% - 52%

To evaluate anemia, polycythemia, and hydration status and to monitor therapy.

To evaluate anemia, polycythemia, and hydration status and to monitor therapy.

Front 6

Schilling test

Back 6

A test that uses oral, radioactive vitamin B12 (cyanocobalamin) and injected, nonradioactive B12 to assess the gastrointestinal absorption of the vitamin.
It is used primarily to diagnose pernicious anemia but can also identify B12 malabsorption caused by other agents, including bacterial overgrowth of the gut and pancreatic insufficiency. A person with normal cyanocobalamin absorption excretes between 8% and 40% of radiolabeled B12 in a 24-hr urine collection taken after the injection. Those with decreased B12 excretion are retested under several conditions:

mammogram

To visualize and assess breast tissue and surrounding lymph nodes for cancer, inflammation, abscess, tumor, and cysts.

Front 8

pap smear

Back 8

To establish a histological diagnosis of cervical and vaginal disease and identify the presence of genital infections, such as cancer, herpes, and cytomegalovirus.
