  1. blood chemistry
    a test of the fluid portion of the blood to measure the presence of a chemical constituent
  2. blood chemistry panels
    specialized batteries of automated blood chemistry tests performed on a single sample of blood; used as a general screen for disease or to target specific organs or conditions
  3. basic metabolic panel
    battery of tests used as a general screen for disease
  4. comprehensive metabolic panel
    tests in addition to basic metabolic panel for expanded screening purposes
  5. blood culture
    a test to determine if infection is present in the bloodstream by isolating a specimen of blood in an environment that encourages the growth of microorganisms
  6. CD4 cell count
    a measure of the number of CD4 cells in the blood; used in monitoring the course of HIV and timing the treatment of AIDS
  7. complete blood count (CBC)
    the most common laboratory blood test performed as a screen of general health or for diagnostic purposes
  8. white blood count (WBC)
    a count of the number of white blood cells per cubic millimeter
  9. red blood count (RBC)
    a count of the number of red blood cells per cubic millimeter
  10. hemoglobin (HGB or Hgb)
    a test to determine the blood level of hemoglobin (expressed in grams)
  11. hematocrit (HCT or Hct)
    a measurement of the percentage of packed red blood cells in a given volume of blood
  12. blood indices
    calculations of RBC, HGB, and HCT results to determine the average size, hemoglobin concentration, and content of red blood cells for classification of anemia
  13. mean corpuscular volume (MCV)
    a calculation of the volume of individual cells in cubic microns using HCT and RBC results: MCV=HCT/RBC
  14. mean corpuscular hemoglobin (MCH)
    a calculation of the content in weight of hemoglobin in the average red blood cell using HGB and RBC results; MCH=HGB/RBC
  15. mean corpuscular hemoglobin concentration (MCHC)
    a calculation of the average hemoglobin concentration in each red blood cell using HGB and HCT results; MCHC=HGB/HCT
  16. differential count
    a determination of the number of each type of white blood cell (leukocyte) seen on a stained blood smear; each type is counted and reported as a percentage of the total examined
  17. red cell morphology
    as part of identifying and counting the WBCs, the condition of the size and shape of the red blood cells in the background of the smeared slide is noted
  18. platelet count (PLT)
    a calculation of the number of thrombocytes in the blood; normal range 150,000-450,000/cubic millimeters
  19. erythrocyte sedimentation rate (ESR)
    a timed test to measure the rate at which red blood cells settle or fall through a given volume of plasma
  20. partial thromboplastin time (PTT)
    a test to determine coagulation defects such as platelet disorders
  21. thromboplastin
    a substance present in tissues, platelets, and leukocytes that is necessary for coagulation
  22. prothrombin time (PT)
    a test to measure the activity of prothrombin in the blood
  23. prothrombin
    a protein substance in the blood that is essential to the clotting process
  24. venipuncture/phlebotomy
    an incision into or puncture of a vein to withdraw blood for testing
