1. A clinical laboratory director is responsible for ensuring all personnel have the appropriate
education and training. Which of the following is the minimum education requirement for a
Clinical Laboratory Scientist (CLS) Generalist license in California?
A) An associate degree in a chemical or biological science.
B) A bachelor's degree with specific coursework in biological and chemical sciences.
C) A master's degree in clinical laboratory science from an accredited program.
D) A doctoral degree in a related field, such as microbiology.
Correct Answer: B
A CLS Generalist license requires a bachelor's degree that includes a minimum of 18 semester
units in biological sciences, 16 semester units in chemistry, and 3 semester units in
mathematics. Options A, C, and D do not meet the specific statutory minimum degree and
coursework requirements defined in the California Business and Professions Code.
2. According to California regulations, which agency is responsible for the enforcement and
administration of the Clinical Laboratory Act?
A) The Centers for Medicare & Medicaid Services (CMS).
B) The California Department of Public Health (CDPH), Laboratory Field Services (LFS).
C) The Clinical and Laboratory Standards Institute (CLSI).
D) The Food and Drug Administration (FDA).
Correct Answer: B
The CDPH, Laboratory Field Services (LFS), is the designated state agency responsible for
licensing clinical laboratories and personnel, and for enforcing the Clinical Laboratory Act
,(California Business and Professions Code, Chapter 3). CMS enforces CLIA at the federal level,
while CLSI and the FDA are non-regulatory or federal entities with different roles.
3. A laboratory is using an FDA-approved test for influenza that has been waived under CLIA.
The lab director wants to implement a new, unapproved procedure for a novel virus. What is
the legal requirement for this new test?
A) The laboratory may perform the test as long as it is for research purposes only and not
reported to a patient.
B) The laboratory must obtain an investigational use exemption from the FDA and ensure
informed consent is obtained.
C) The laboratory must validate the test's performance characteristics and obtain
authorization from CDPH LFS before reporting results.
D) The laboratory may begin reporting results immediately if it follows the manufacturer's
instructions.
Correct Answer: C
Before reporting patient test results for a non-FDA-approved test, the laboratory must
validate the test's performance specifications (e.g., accuracy, precision) and obtain express
authorization from the CDPH LFS. Options A and D lack the necessary regulatory oversight,
while option B is related to clinical trials but not the primary state requirement for laboratory
reporting.
4. A CLS receives a blood specimen from a patient in the emergency department. The
physician's order is for a Complete Blood Count (CBC). The CLS notes that the specimen is
severely hemolyzed. What is the most appropriate first step?
A) Perform the CBC as requested and report the results with a comment about hemolysis.
B) Immediately call the physician and request a redraw.
C) Discard the specimen and document the reason for not performing the test.
D) Reject the specimen and notify the emergency department (ED) that a new specimen is
required for accurate results.
Correct Answer: D
Standard laboratory protocol requires rejecting a suboptimal specimen, such as a severely
hemolyzed one, and notifying the ordering unit. This ensures patient safety and result
accuracy. While calling the physician (B) may be necessary later, the primary step is to reject
the sample and notify the appropriate personnel. Performing the test (A) could yield
inaccurate results, and discarding it without notification (C) is improper procedure.
,5. According to California Law, what is the maximum civil penalty for a first violation of the
Clinical Laboratory Act?
A) Up to $1,000 per violation.
B) Up to $2,500 per violation.
C) Up to $5,000 per violation.
D) Up to $10,000 per violation.
Correct Answer: B
California Business and Professions Code Section 1312 specifies that the maximum civil
penalty for a first violation of the Clinical Laboratory Act is up to $2,500. The amount may
increase for subsequent violations. This is a fundamental regulatory fact that candidates are
expected to know.
6. A medical laboratory technician (MLT) is performing a differential cell count. They are
concerned about a potential reporting error after the results have already been released.
What is the legally required procedure?
A) Correct the result in the laboratory information system (LIS) and note the date and
correction as an addendum.
B) Do nothing, as errors are considered normal and acceptable if caught in a timely manner.
C) Correct the result in the LIS and delete the original entry to prevent confusion.
D) Send a new corrected report to the physician without noting the previous error.
Correct Answer: A
All entries into the medical record must be accurate and permanent. Corrections must be
made by adding an addendum that clearly marks the date and time of the correction, as well
as the reason for it. Deleting the original entry (C) is prohibited, as it compromises the
integrity of the record and may be considered falsification. Silence (B) is unacceptable.
7. A CLS is performing a quality control (QC) run for a chemistry analyzer. A single control
value is just outside the manufacturer’s acceptable range (±2 SD). The test’s expected range
for clinical decision-making is unaffected by this small deviation. What is the appropriate
course of action?
A) Report patient results as long as the clinical decision range is unaffected.
B) Re-run the same QC material to see if the result falls within range.
C) Follow the laboratory’s established written corrective action policy and documentation
, procedure for QC failures.
D) Adjust the analyzer's calibration to bring the QC value within range.
Correct Answer: C
Whenever a QC result is outside the acceptable limits, the laboratory must follow its
established procedures for investigating and documenting the failure, regardless of the
potential clinical impact. This ensures a systematic approach to identifying and correcting the
root cause. Options A, B, and D represent informal actions that circumvent the required
documented process.
8. Which of the following is a CLIA requirement for quality control (QC) performed in a
moderate-complexity laboratory?
A) QC must be performed at least once every week.
B) QC must be performed each day of patient testing.
C) QC must be performed each time a new reagent lot number is opened.
D) The frequency of QC is determined by the laboratory director.
Correct Answer: B
For moderate-complexity testing, CLIA regulations require that quality control materials be
tested at least once each day of patient testing. Frequency can be increased based on
manufacturer recommendations or lab policy. Options A and C are insufficient or incomplete,
while option D is incorrect as the frequency is mandated, not determined solely by the
director.
9. In the context of a clinical laboratory, what is the primary purpose of the Chain of Custody
(CoC) form?
A) To document the specimen's path from collection to disposal.
B) To track specimens for forensic or legal purposes to ensure an unbroken record of
possession.
C) To provide billing information for the patient's insurance.
D) To record the patient's consent for the testing procedure.
Correct Answer: B
The primary purpose of the CoC form is to legally document the chronological history of a
specimen, showing who collected, handled, transferred, and analyzed it. This is critical for
legal proceedings to ensure the evidence has not been tampered with. Options A, C, and D
describe other aspects of laboratory documentation and patient care, but not the specific
purpose of the CoC.
