skin cancer associated with Merkel cell polyomavirus.
What is the most likely source of infection in serological testing?
contact with patient specimens.
What are Universal Precautions?
instituted by the CDC in 1985 to protect health-care workers from exposure to blood-borne pathogens, primarily hepatitis B virus (HBV) and HIV.
What is Body Substance Isolation (BSI)?
modification of universal precautions that is not limited to bloodborne pathogens and considers all body fluids and moist body substances to be potentially infectious.
What is a disadvantage of Body Substance Isolation (BSI)?
it does not recommend handwashing after removing gloves unless visual contamination is present.
What are Standard Precautions?
The major features of Universal Precautions and Body Substance Isolation have now been combined
What is the ultimate goal of biological safety?
prevent completion of the chain by preventing transmission.
What is a Reservoir in the context of infectious agents?
Where infectious agent can live and multiply, such as a contaminated clinical specimen or an infected patient (e.g., body fluids, fomites).
What is the most frequently encountered specimen in immunological testing?
Serum
How should serum be handled if testing cannot be performed immediately?
Serum may be stored between 2 - 8 °C for up to 3 days
serum should be promptly separated for how many mins without transferring any cellular elements
What should be done if testing cannot be done within 72 hours?
serum should be frozen at -20 °C.
How should biological waste be disposed of?
All biological waste, except urine, must be placed in appropriate containers labeled with the biohazard symbol.
What does OSHA require for chemicals and reagents containing hazardous ingredients?
if its concentration is greater than 1%, must have a Material Safety Data Sheet (MSDS) on file in the work area.
What must be available for reference in the immunology section of the laboratory (CLSI guidelines)?
A procedure manual (paper or digital) containing all the procedures performed in the immunology section of the laboratory must be available for reference in the working area.
What does Quality Control refer to?
materials, procedures, and techniques that monitor the accuracy, precision, and reliability.
What are External Controls?
used to verify the accuracy and precision of a test. The control material is exposed to the same conditions as the patient samples.
What are Internal Controls?
also called procedural controls, consist of internal monitoring systems built into the test system.
What are Electronic Controls?
use a mechanical or electrical device in place of a liquid specimen. This type of QC can be an internal or an external component inserted into a point-of-care (POC) instrument.
What does Personnel Assessment include?
includes education and training, continuing education, competency assessment, and performance appraisals.
What is the most common method for reporting results?
Electronic transmission
HTLV-3
Previous HIV
Internal controls
Monitor the sufficient addition of a px spx or reagent, the instrument and reagent interaction and for lateral flow test methods, whether sample migrated through test strip properly
