Lactate Dehydrogenase (LDH, LD)
mesurement of thetime taken for clot formationafter adding thromboplastin and calcium tocitrated plasma
Prothrombin Time (PT)
Evaluation of the functioning of thecoagulation sequence. Screening process used for coagulation disorders and effectiveness ofheparin therapy
Partial Thrombolastin Time (PTT)
Measurement oftime required for the platelet clot to form; often measured by theIvy Method
Bleeding Times
Measurement ofrate at which RBCS fall out of well-mixed whole bloodto the bottom of aspecial vertical test tube
ESR – Erythrocyte Sedimentation Rate
Measurement of theblood glucose bound to hemoglobin
Glycosylated Hgb/ Glycohemoglobin
Glycosylated Hgb gives an overall view of the past ___ days of glucose saturation
120
Amount ofglucosefound in blood after8 hours of fasting
Fasting Blood Glucose (FBS levels)
Evaluates patients who have symptoms ofdiabetes mellitus,diabetic complications,screening for gestational diabetes
GTT Glucose Tolerance Test
Blood glucose levels2 hoursafter ingestion of a normal meal, usually lunch
2 HourPostprandial
List some measurements done as part of urinalysis
pH, specific gravity, color, odor, presence ofketones, proteins, sugars, bilirubin and urobilinogen, presence ofabnormal blood cells, casts, bacteria, other cells and crystals
Test done to detect occult blood in stool
Guaiac tests
Excisionof tissue from the living body, followed bymicroscopic examinationfor purpose of finding diagnosis
Biopsy
Electrodiagnostic assessmentand recordign of the activity of theskeletal muscles; study assessing the state of themuscle at rest and during contraction
Electromyelogram
Intradermal injection oftuberculingiven on the inner aspect of the lower arm; results read in 48-72 hours
Tuberculosis Screening/Mantoux Test
Specimens obtained fromvarious tissues and fluidsand placed on a medium to grow and then studies formicrobes.Specimen also placed on a disk with variousantibioticsto determine which one will be effective in destroying the microbe.
Culture (growing in medium) and Sensitivity (microbe vs antibiotics)
A surgical procedure towithdraw spinal fluidfor analysis
Lumbar Puncture
Used to diagnosepernicious anemia and peptic ulcers. Contents of stomach are analyzed foracidity, appearance and volume.
Gastric Analysis
Studies of thefunctioning or nonfunctioningof a patient’simmue system
Immune and Immunoglobin Studies
Used to diagnose pregnancy, abortion, ectopic pregnancy and uterine pathology
Pregnancy TestsHuman Chronic Gonadotropin, hCG/UCG
Aspiration ofbone marrowby needle from the sternum, posterior superior iliac spineor theanterior iliac crestto diagnose neoplasms, metastasis and blood disorders
Bone Marrow Studies
Recording of theElectrical activityof thecerebral cortexof the brain to locate insult tocerebral tisuse
Electroencephalogram
Infectious disease drug category must be taken atthe first sign of symptomsto be most effective
Antivirals
Drug category is also known asantimalarials
antiprotozoals
