Study Notes

Quality Control Tools

The Levey-Jennings chart is utilized for graphical presentations of quality control values over time.
A "shift" indicates an abrupt change in the mean of quality control values.

Testing Characteristics

Qualitative examinations yield non-numerical results, important for certain testing contexts.
Calibrators are essential as they contain known analyte amounts to ensure accurate measurements.

Quality Management

Quality indicators assess how well an organization meets operational performance expectations.
Point of care testing is a term for testing performed at the location of patient care, such as at the bedside.

Regulatory Compliance

Calibration verification involves using materials of known concentration to ensure calibration accuracy under CLIA law.
The FDA determines the complexity of laboratory test systems.

Legislation and Testing Standards

The FDA Modernization Act of 1997 established simpler methodologies for waived testing under CLIA 1988, ensuring minimal risk of erroneous results.

Clinical Laboratory Techniques

Electrophoretic devices separate proteins but do not measure emission spectra.
Absorbance calculation from %T is done using the formula: 2 - log %T.
Spectrophotometry is based on the selective absorption or emission of electromagnetic energy by substances at different wavelengths.
Agarose gel is a support material in electrophoresis used to separate proteins by charge and size.

Biosafety and Best Practices

Handling of TB materials requires laboratories to operate at a biosafety level of 2+ or 3.
Prohibition of mouth pipetting is an established best practice to prevent contamination and ensure safety.

Safety Regulations

New Safety Data Sheets (SDS) will include 16 specific sections to present information consistently.
Epstein Barr Virus (EBV) is not classified as a bloodborne pathogen, unlike HBV, HCV, and HIV.
