Which of the following types of tests is a phlebotomist allowed to perform according to CLIA regulations?
Occult blood detection
Flow cytometry
Genetic molecular
Electrophoresis
The Correct Answer is A
Choice A Reason:
Occult blood detection is a test that a phlebotomist is allowed to perform according to CLIA regulations. This test is typically used to detect hidden blood in the stool, which can be an early sign of colorectal cancer or other digestive system diseases. It is considered a waived test under CLIA, meaning it is simple and carries a low risk for an incorrect result.
Choice B Reason:
Flow cytometry is a complex test that requires specialized training and equipment. It is used to analyze the physical and chemical characteristics of particles in a fluid as they pass through at least one laser. Phlebotomists are not typically trained to perform this type of analysis, as it falls under the category of high complexity testing.
Choice C Reason:
Genetic molecular tests are used to detect specific sequences in DNA or RNA that may or may not lead to disease. These tests are complex and require specialized knowledge and equipment. They are not within the scope of practice for phlebotomists, who are trained primarily in blood collection.
Choice D Reason:
Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge. This type of test is also complex and requires specialized training and equipment, which is beyond the scope of a phlebotomist's duties.

Correct Answer is A
Explanation
Choice A Reason:
Taking the specimen temperature before 4 minutes is the correct procedure according to the Department of Transportation (DOT) guidelines. The DOT Rule 49 CFR Part 40 Section 40.65 states that the temperature of the specimen must be checked no later than four minutes after the employee has given the specimen. The acceptable temperature range is 32–38 °C/90–100 °F, which helps to verify the validity of the specimen.
Choice B Reason:
Taking the specimen temperature at 5 minutes is not within the DOT guidelines. The temperature must be taken before 4 minutes have passed to ensure the specimen's integrity and to comply with the regulatory requirements.
Choice C Reason:
At 15 minutes, the temperature check would be too late. The DOT guidelines specify that the temperature should be checked no later than four minutes after collection to ensure the specimen has not been tampered with and is within the acceptable temperature range.
Choice D Reason:
After 30 minutes, the temperature of the urine specimen would not reflect the body temperature at the time of collection, which is necessary for the validity of the test. This delay could allow for the temperature to fall outside of the acceptable range, potentially invalidating the specimen.
Correct Answer is B
Explanation
Choice A Reason:
Serology is the division of the laboratory that deals with the study of blood serum. In serology, the focus is on identifying and measuring antibodies in the serum. While serology can be used to support the diagnosis of infections, it does not involve culture and sensitivity testing, which is specific to identifying pathogens and determining their susceptibility to antibiotics.
Choice B Reason:
Microbiology is the correct division for culture and sensitivity tests. This division specializes in studying microorganisms, including bacteria, fungi, parasites, and viruses. When a culture and sensitivity test is ordered, it is the microbiology lab that cultures the sample to grow the organism and then tests various antibiotics to determine which are most effective against it.
Choice C Reason:
Histology is the study of the microscopic structure of tissues. Histology labs prepare and examine tissue samples to diagnose diseases, but they do not perform culture and sensitivity tests, which are specific to microbiology.
Choice D Reason:
Chemistry is a division of the laboratory that performs a wide range of tests to measure chemicals and enzymes in the body. These tests can include blood glucose levels, liver enzymes, and hormone levels, among others. However, chemistry does not handle culture and sensitivity testing, as this is not within the scope of chemical analysis.
