Activated Partial Thromboplastin Time (aPTT)

A coagulation assay evaluating the intrinsic and common pathways, monitored during Heparin therapy.

Quality Assurance (QA)

A broad, continuous, proactive system monitoring all operational steps across the laboratory workflow to prevent errors and ensure accurate, timely, and safe patient outcomes.

Quality Control (QC)

A targeted operational component of Quality Assurance involving the analysis of known control materials alongside patient samples to evaluate precision and accuracy.

Pre-Analytic Phase

The phase of laboratory testing encompassing all operational steps occurring prior to specimen analysis (ordering, collection, labeling, transport, and processing), where the majority of errors occur.

Analytic Phase

The testing phase where the actual analytical test protocol is executed on autoanalyzers or manual benches following standard operating procedures, calibration, and daily QC runs.

Post-Analytic Phase

The phase of laboratory testing following analytical completion, involving technical verification, clinical validation, notification of critical values, turnaround time tracking, reporting, and waste disposal.

Trend (L-J Chart)

A continuous, gradual movement of control values in one direction over 6 or more consecutive runs, typically caused by system deterioration such as reagent degradation or aging light sources.

Shift (L-J Chart)

An abrupt change where control values fall consistently on one side of the Mean for 6 or more consecutive runs, caused by sudden system changes like a new reagent lot or recalibration.
