6. HEMATOLOGY &
COAGULATION
◦ Enumeration of cells in the blood and other
body fluid
◦ CBC: complete blood count: RBC count, WBC
count, Platelet count
◦ Hemoglobin, Hematocrit
◦ WBC differential count: Neutrophils,
Eosinophils, Basophils, Monocytes, Blast cells if
any
◦ Blood indices: MCV: mean corpuscular volume,
MCH: mean corpuscular hemoglobin, MCHC:
mean corpuscular hemoglobin concentration,
RDW: red cell distribution width
◦ Coagulation studies: PT: prothrombin time,
aPTT: activated partial thromboplastin time
13. LABORATORY TESTING CYCLE
◦ Pre-analytic: receipt of laboratory request, patient preparation, specimen collection, specimen transport
◦ Variables that may affect the test results
◦ Analytic: actual testing
◦ Equipment, instruments, reagents used, quality control program
◦ Post analytic: transmission of test results, turn around time
14. QUALITY ASSURANCE
◦ Activities to ensure reliability of test results
◦ Organized, systematic, well planned and regularly done
◦ Documented and reviewed
◦ Internal quality assurance: day to day activities
◦ External quality assurance: checking performance among clinical laboratories facilitated by NRL-DOH
◦ NKTI: hematology & coagulation
◦ RITM: microbiology & parasitology
◦ LCP: clinical chemistry
◦ EAMC: drugs of abuse & toxicology
◦ SACCL: infectious disease: HIV, HBV, HCV
