Quality assesment Ensuring lab results. are up to date, meet industry standards and are accurate. A doctor's diagnosis and treatment for the patient are based on lab test results. Ensuring that the lab provides accurate gets the patient proper care,
CLIA 88 Quality control legislation enacted in response to lab testing errors. Established minimum thrasholds for all tests. All labs must meet QC standards. minimum requirments for non waived tests.
COLA Commission of Office Laboratory Accreditadtion Overseas small private practice labs.
Control specimen with known value similar to compostion to patient's blood.
Precision how close test results are to eachother
accuracy how close a test is to the true value
standard highly purified substance of a known composition. May or may not be simiar to patient specimen.
variance fluctuations that impact measurement of substance
specifity ability of test to identify those without disease giving a negative result . Highly specific tests eliminate false positives.
sensitivity ability of test to indetify those with disease giving a positive result. The more senstive a test is the fewer false negatives.
Levy-Jennings Chart a chart for graphing QC data to show if a lab test is working well
Trend uninterrupted rise or decline away from the mean on a Levy-Jennings chart.
Shift value above or below the mean that is non consecutive or sporadic. on a Levy-Jennings chart.
Reference value range in values for a phsyiological measurment in a healthy person.

tourniquet restricts blood flow to make finding vein easier.
plasma fluid portion of anticoagulated blood
serum portion of blood that has clotted
anticoagulants additives that prevent clotting by capturing calcium, or prohibiting thrombin formation
thrombin a clotting factor the links with fibrinogen to form a fibrin clot.
EDTA binds calcium provides whole blood. Prevents platlet aggregation. Usually a powder.
Citrate binds calcium for coagulation tests. Tests plasma. Tubes must be filled completely to prevent artificially prolonged clotting time test results. Needs to be centrifuged before testing.
Hepain inhibits thrombin formation.
Oxalates Binds calcium and provides plasma for glucose testing.
ACD DNA and HLA testing binds calcium. Acid citrate dextrose. Regular sized yellow top tube.
CPD Citrate phosphate dextrose used for blood dation unit bags. citrate binds calium. Phosphoruos stabalizes PH.
SPS Sodium polyestronae sulfate in blood culture tubes. Binds calciums and reduces compliments and slows phagocytes
compliments stop microorganisms in blood.
phagocytes WBC that destroy bacteria.
antiglycolytic agents additives that stop glycolysis.
glycolysis break down of glucose. RBCs use glucose as a nutrient source
Sodium floride an antiglycolytic agent that prevents glycolysis for 3 days and inhibits bacteria growth needs to be inverted 8 times
Coagulants provide more surface area for plateletes to aggregate. Needed for serum. Examples are silica particles, cellyte and thrombin
SST Serum separator tubes use a thyrotropin gel with s adensity between that of cels and serum and cells in plasma. Needs to e inverted and centrifuged.
