AAB BASIC KNOWLEDGE EXAM STUDY GUIDE
2026 FULL QUESTIONS AND SOLUTIONS
ALREADY PASSED
● most common post-analytical error - clerical error
● how often a procedure be reviewed: - every 2 years before inspection
● thermometers must be checked against NIST thermometer - annually
● following equipment maintenance, when is QC suggested? - After any
preventative maintenance
● according to CLIA who is responsible for processing, testing, and
reporting results? - testing personnel
● NOT a duty to testing personnel - interpretation of highly complex
testing
● some requirements for the employee personal records: - continuing
education
,training
remedial action documentation
annual performance appraisal
● OSHA requires that the original label contain all these information -
Product name
Hazard warning
Manufacture's name and address
● what is the level of complexity of the most testing performed in
clinical laboratories? - moderately complex
● CLIA required inspectrion, how often? - every 2 years
● labs that DO NOT require to participate in proficiency testing - waived
testing only
● CLIA performance criteria - Failed 2 analytes in 1 PT event
Failed 3 analytes in 1 PT event
Failed the same analytes in 2 consecutive PT event
Failed 2 different analytes in the last 2 pt event
,● alternative proficiency testing example: - splits samples to another
facility using the same test method
● what does MSDS mean? - Material Safety Data Sheet
● complexity test is regulated by: - CLIA
● checking centrifuge and the rpm. Equipment and Maintenance is :
called - Quality Control
● Pre-Analytical- Quality assurance Lab request - specimen collection
patient identification
venipuncture process
specimen rejection
● analytical phase- proficiency testing, QC program - equipment
calibration
Quality Control procedure
specimen integrity
● Post-Analytical- quality assurance - result reporting
critical values
notification guidelines
, ● what should be included in the record filee of the worker personnel? -
HIPAA regulation known by the employee
● The blue filter modifies the yellow effect on the light giving it a more
white light effect - to eliminate the yellow color emitted by the tungsten
light bulb
● the oil immersion is used for? - it gathers light for the objective and
increase resolution. type B (high viscosity) is commonly used.
● The X and Y in the microscope are used for: - the values obtained
bared plotted on the x and y axis. This moves the mechanical stage or
base left to right and the y moves up and down or front to back.
● sharp container is an: - engineering control
● NO sharps is in: - Biohazard bag
● precision means: - closeness of repeat results (reproducibility).
describes how close test results are to one another when repeated
analysis of the same material is performed.
