---|---|
The study of blood group antigens and antibodies | immunohematology or blood banking |
Pathogens that may be present in human blood and that may cause diseases in humans | blood borne pathogens |
A hematocrit preformed on a small amount of blood | microhematocrit |
Swelling of tissue around a vessel due to leakage of blood into the tissue | hematoma |
The form and structure of cells, tissues, and organs | morphology |
A determination of the relative numbers of each type of leukocyte in a stained blood smear | differential count |
The appearance on an antibody in the serum of an individual following exposure to an antigen | seroconversion |
Rapid increase in immunoglobulins following a second exposure to an antigen | anamnestic response |
The functional unit in the kidney is the | nephron |
The normal pH of urine | 4.5 to 8.0 / 5.5 to 8.0 |
During chemical urinalysis ketones test for | incomplete fat metabolism, acetone, acetoacetic acid, and beta-hydroxybutyric acid |
During chemical urinalysis nitrates test for | conversion of urinary nitrates to nitrites |
During microscopic urine evaluation casts are seen | low-power 10x to locate then high-power 40x to identify |
During microscopic urine evaluation epithelial cells are identified | high-power 40x |
During chemical urinalysis glucose test for | presence of glucose |
The normal value for urine glucose is | negative |
During chemical urinalysis bilirubin test for | hemoglobin breakdown |
The normal value for urine bilirubin is | negative |
The normal value for urine nitrate is | negative |
The normal value for urine ketones is | negative |
What does urine pH analyze or determine | degree of acidity or alkalinity of the urine |
During chemical urinalysis what does blood test for | hemoglobin and intact RBCs |
What is the normal value of urine blood | negative |
During chemical urinalysis what does the leukocyte test detect | presence of WBCs in urine |
Abnormal urine chemical test would indicate what for nitrite | UTI |
Abnormal urine chemical test would indicate what for glucose | diabetes |
Abnormal urine chemical test would indicate what for leukocytes | infection or inflammation |
Abnormal urine chemical test would indicate what for blood | infection, bleeding in kidneys, glomular damage, tumor, trauma to the urinary tract |
Abnormal urine chemical test would indicate what for protein | renal disease or UTI |
Abnormal urine chemical test would indicate what for ketones | uncontrolled diabetes, starvation, prolonged dieting or fasting |
Abnormal urine chemical test would indicate what for bilirubin | liver disease, bile duct obstruction, hepatitis |
Abnormal urine chemical test would indicate what for urobilinogen | hepatic or hemolytic disease |
What does urine specific gravity reflect | kidneys ability to concentrate urine |
The cellular elements found in blood include | RBCs (erythrocytes), WBCs (leukocytes), and platelets (thrombocytes) |
The function and lifespan for erythrocytes is | transport oxygen to the tissue and carbon dioxide to lungs/120days |

The ESR test is an indicator of | inflammation and or tissue injury |
Medical conditions which increase the ESR result | pregnancy, anemia, macrocytosis, inflammatory disease, cancer, TB, increased plasma fibrinogen & globulin, acute & chronic infections |
Medical conditions which decrease the ESR | sickled cells, polyerythremia, spherocytosis, microcytosis, and increased plasma velocity |
