CLIA Flashcards
What are lab/facility exceptions to CLIA standards?
Forensic testing
research labs that don’t report patient results
NIDA certified labs which perform drug testing
*other testing at NIDA lab is subject to CLIA
What are the 7 criteria used by FDA to determine test complexity and categorize tests?
1) scientific/technical knowledge
2) training and experience required
3) reagents/materials preparation, stability, reliability
4) operational steps
5) calibration, QC, proficiency testing materials availability
6) test system troubleshooting and equipment maintenance
7) interpretation and judgment required to perform all 3 phases of testing
How is testing categorized between moderate and high complexity with the scorecard?
7 criteria scored from 1-3 with 1 being lowest
7 scores added together
12 OR LESS = moderate complexity
ABOVE 12 = high complexity
List the 5 CLIA certificates
1) Registration
2) Waiver
3) PPM procedures
4) Compliance
5) Accreditation
For how long are CLIA certificates valid?
2 years
Which level of complexity in labs requires registration certificate?
all labs performing moderate or high complexity or both
labs performing only WAIVED, PPM, or combination are NOT required to obtain registration certificate
only labs applying for compliance or accreditation cert will receive registration cert.
issued to labs performing non-waived testing until CLIA inspection occurs
Initially for all laboratories performing test procedures of moderate complexity (other than the subcategory of PPM procedures) or high complexity, or both; and
(2) For all laboratories that have been issued a certificate of waiver or certificate for PPM procedures that intend to perform tests of moderate or high complexity, or both, in addition to those tests listed in § 493.15(c) or specified as PPM procedures.
How complex are PPM procedures considered?
Moderate complexity
List examples of accreditation programs approved by HHS
CAP, COLA, JCAHO
Do labs with several locations require separate applications for CLIA certificates? What are the exceptions?
YES
exceptions: mobile units, health screening fairs, temporary testing locations can be covered under cert of primary site
not for profit fedreral, state or local government labs that perform limited public health testing (no more than combination of 15 moderately complex or waived tests per certificate
labs within a hospital with contiguous buildings on same campus and under common direction
What are the time limits for reporting changes to CMS?
30 days: ownership, name, location or director or technical supervisor
6 months: tests within specialty or subspecialty not included on compliance certificate
6 months: deletions or changes in test methodologies for tests included in specialty or subspecialty or both contained in compliance Cert
What are characteristics of waived tests?
1) fully automated or self-contained
2) use only unprocessed specimens
3) require no specimen manipulation before analytic phase
4) no operator intervention during analytic phase
5) direct readout of results - no calculations or conversions
6) contain fail-safe mechanisms that render no result when system malfunctions or initiates fail-safe mechanisms rendering no result when result is outside of reportable range
7) no invasive test system troubleshooting, electronic, or mechanical maintenance
8) instructions are written at 7th grade comprehension level
Who can perform PPM procedures?
physician,
midlevel practitioner under physician supervision or independent practice if state authorizes it
dentist
only during patient’s visit on specimen obtained from his patient or patient in group practice
What are main specifications of PPM procedures?
Moderate complexity
Instrument is bright-field/phase-contrast microscopy
specimen is labile
CONTROLS NOT AVAILABLE to monitor entire testing process
LIMITED specimen handling or processing required
what are examples of PPM procedures?
wet mount preparations for presence or absence of bacteria, fungi, parasites, human cellular elements
KOH preparations
pinworm examinations
fern tests
post coital, direct exams of vaignal or cervical mucous
urine sediment exams
nasal smears for granulocyts
fecal leukocyte
qualitative semen analysis
What are the requirements of PPM labs?
PT, patient test management, quality control, personnel and quality assurance
subject to inspection
What is considered satisfactory performance on PT testing?
80% correct for each analyze in most specialities
some immunohematology procedures and compatibility testing require 100% accuracy
What is considered Unsatisfactory PT performance?
failure to attain minimum satisfactory score for an analyte, test or subspecialty for testing event and requires remedial actions
What is considered unsuccessful PT?
unsatisfactory performance for SAME ANALYTE in 2 consecutive or 2/3 testing events
repeated unsatisfactory OVERALL testing event scores for 2 consecutive or 2/3 testing events for same specialty or subspecialty
unsatisfactory testing event score for those subspecialties not graded by analyte (Bacteriology, mycobacteriology, virology, parasitology, mycology, compatibility testing, unexpected antibody detection, antibody identification) for SAME subspecialty for 2 consecutive or 2/3 testing events
How long must documentation of PT records be maintained
minimum of 2 years from proficiency testing event
Is PT required for all test methods, systems or examinations during PT event?
NO only required for primary method used in patient testing
How should PT samples be tested?
With regular workload by personnel who routinely perform testing and with routine methods
For which specialities and subspecialties is satisfactory performance on PT considered 80% correct for each analyte you are being tested on?
microbiology (bacteriology, mycobacteriology, mycology, parasitology, virology)
diagnostic immunology (syphilis serology, general immunology)
chemistry (routine chemistry, endocrinology, toxicology)
hematology (no subspecialties defined here)
What is considered satisfactory PT performance in immunohematology subspecialties?
ABO/RHO 100%
Unexpected Antibody 80%
Compatibility testing 100%
Antibody identification 80%
What is considered satisfactory performance for most PT testing?
80% correct for each analyze you are being tested on ( 4/5 right per testing event)
Testing involves multiple samples of the same analyte
