Def First Med Term Flashcards
Screening test that assesses the rectal wall surface for lesions or abnormally firm area that might indicate cancer
Digital rectal exam (DRE)
Self-examination of the testes for abnormal lumps or swellings in the scrotal sac.
Testicular self-examination
Test to determine the presence of pathogens in the blood stream
Blood culture
Series of tests that includes hemoglobin: hematocrit: RBC, WBC, and platelet counts; differential WBC count; RBC indices and RBC and WBC morphology
complete blood count (CBC)
Test that enumerates the distribution of the WBC’s in a stained blood smear by counting the different kinds of WBCs and reporting each as percentage of the total examined. Commonly used as a first step in diagnosing a disease.
Differential count (diff)
Measurement of the distance RBCs settle to the bottom of a test tube under standardized condition; also called sed rate. Elevated ESR is associated w/ inflammatory diseases, cancer, and pregnancy, but decreases in liver dz.
Erythrocyte sedimentation rate (ESR)
Measurement of the amoutn of hemoglobin found in awhile blood sample. Hgb values decrease in anemia and increase in dehydration, polycythemia vera and thrombocytopenia purpura.
Hemoglobin (Hgb) value
Measurement of the percentage of RBC’s in a whole blood sample
Hematocrit (Hct)
Non specific rapid serological test for infectious mononucleosis; also called the heterophile antibody test
Monospot
Test that measures the length of time it takes blood to clot. It screens for deficiencies of some clotting factors and monitors the effectiveness of anticoagulant (heparin) therapy; also called activated partial thromboplastin time (APTT)
Partial thromboplastin tissue (PTT)
Test that measures the time it takes for the plasma portion of blood to clot. It is used to evaluate portions of the coagulation system; also called pro time. Commonly used to manage patients receiving the anticoagulant warfarin (Coumadin)
Prothormbin time (PT)
Mathematical calculation of the size, volume, and concentration of hemoglobin for an RBC.
Red blood cell (RBC) indices
Test used to assess the absorption rate of radioactive vitamin B12 by the digestive system. Definitive test for diagnosing pernicious anemia because vitamin B12 isn’t absorbed in this disorder and passes out of the stool.
Schilling test
Radiographic examination of lymph nodes after injection of a contrast medium
Lymphadenography
Endoscopy of the urinary bladder for evidence of pathology, obtaining biopsies of tumors or other growth, and removal or polyps.
Cystoscopy
Endoscopy of the kidney(s) using a specialized, three-channel endoscope that enables visualization and irrigation of the kidney.
Nephroscopy
Endoscopy of the urethra using a specialized endoscope, typically for lithotripsy or TURP
Urethroscopy
Test that determines the amount of urea nitrogen, a waste product of protein metabolism, present in a blood sample (used as an indicator of kidney function)
Blood urea nitrogen (BUN)
Test that determine the causative organism of a disease and how the organism respond to various antibodies.
Culture and sensitivity (C&S)
Blood test used to detect prostatic disorders, especially prostatic cancer (level is elevated in prostatitis, benign prostatic hyperplasia, and tumors of the prostate)
Prostate-specific antigen (PSA)
