Common Testing Errors and Phases in Laboratory Quality Assurance

Flashcards covering key terminology and concepts related to common testing errors and the phases of laboratory quality assurance.

Common Testing Errors

Errors that arise during testing due to human mistakes, including specimen mislabeling and improper instructions.

Preanalytical Phase

The stage where a test is ordered, specimens are collected and labeled, and any errors can impact subsequent testing.

Mislabeled Specimens

Specimens that are incorrectly labeled, leading to potential testing discrepancies and inaccurate results.

Patient Adherence

The extent to which a patient follows provided instructions for test preparation, crucial for accurate test results.

Analytic Phase

The stage in quality assurance where instruments are calibrated, tests are conducted, and results are analyzed and documented.

Postanalytical Phase

The final stage of testing where results are interpreted, reported, and documented, ensuring communication with the patient.

Equipment Malfunctions

Failures or issues with laboratory equipment that can lead to inaccurate test results if not properly maintained.

Inappropriate Test Request

Requesting a test that is not suitable for the patient’s condition, leading to possible inaccuracies.

Accurate Recording

The essential process of systematically documenting all relevant test information in the patient's health record.

Excessive Turnaround Time

Delays in reporting test results, which can impede timely patient care.

Sample Mix-Up

A significant error during testing where specimens are incorrectly switched or confused with one another.
