Laboratory Testing and Quality Control chapter 44

These flashcards cover key terminology and concepts related to laboratory testing, quality control, and immunology.

Quality Control

Procedures to ensure accuracy and reliability of diagnostic test results.

Hemoglobin

A protein in red blood cells that transports oxygen to the body.

Hematocrit

Percentage of red blood cells in a blood sample.

Anemia

Condition characterized by a deficiency of red blood cells or hemoglobin.

ESR (Erythrocyte Sedimentation Rate)

Rate at which red blood cells settle in a calibrated tube, used to assess inflammation.

CBC (Complete Blood Count)

A blood test that measures red blood cells, white blood cells, platelets, and hemoglobin.

Glucose Tolerance Test (GTT)

A test to determine how well the body processes glucose.

Glucometer

A device for measuring blood sugar levels.

CLIA (Clinical Laboratory Improvement Amendments)

Regulations overseeing laboratory testing to ensure accuracy and reliability.

Capillary Blood

Blood obtained by pricking the skin, often used for point-of-care testing.

Panic Values

Laboratory results that require immediate medical attention due to their severity.

HCG (Human Chorionic Gonadotropin)

Hormone tested for in pregnancy tests.

Platelets

Cells in the blood that help with clotting.

Lysozymes

Enzymes that break down bacterial cell walls and are part of the immune response.

Immunology

The study of the immune system and its responses.

Phenylalanine

An amino acid that cannot be metabolized by individuals with PKU.

Antigen

Any substance that triggers an immune response.

Antibodies

Proteins produced by the immune system to identify and neutralize foreign objects.
