Point of Care Testing Flashcards
What does CLIA stand for?
Clinical Laboratory Improvement Amendments
CLIA was established to ensure the quality of diagnostic testing through laboratory regulations.
What is CLIA-waived testing?
The simplest form of testing of all laboratory procedures
CLIA-waived tests are typically performed in ambulatory care centers and pose minimal risk of incorrect results.
What are the three designations for laboratory testing based on complexity?
- CLIA-waived
- Moderate-complexity
- High-complexity
CLIA-waived is the lowest level of complexity and is the most common in ambulatory care.
What must labs performing moderate- and high-complexity tests have?
A CLIA certificate and undergo inspections
These tests are typically performed in reference or hospital laboratories.
What is an example of a provider-performed microscopy procedure?
Microscopic screening of urine or body excretions
This allows the provider to develop a preliminary diagnosis and begin treatment.
What is the most commonly tested specimen in an ambulatory care setting?
Urine
Various means exist for collecting urine specimens.
What is a random urine specimen?
A sample collected at any time of the day for screening purposes
The patient urinates in a clean, nonsterile container.
What is the purpose of the first morning urine specimen?
It is more concentrated and often used for pregnancy testing or evaluating other analytes
The patient collects their first urine specimen of the morning in a clean container.
Describe the clean-catch midstream urine collection method.
The patient cleans the genitalia area, begins urinating in the toilet, then collects urine in a sterile container
This method is used for cultures or when a noncontaminated specimen is required.
What is a 24-hour urine sample collection method?
A method using a large container where the patient collects all urination specimens for 24 hours
This type of collection is important for quantitative analysis of components such as protein.
