Which of the following information should be included in the chain of custody following a blood alcohol testing procedure?
The timeline of the individual prior to specimen collection
The identity of each person who handles the specimen
The physical and mental status of the individual before and after
The condition of the specimen every hour
The Correct Answer is B
Choice A Reason:
The timeline of the individual prior to specimen collection is important for context but is not typically part of the chain of custody documentation. The chain of custody focuses on the handling of the specimen rather than the activities of the individual before the collection.
Choice B Reason:
The identity of each person who handles the specimen is a critical element of the chain of custody. This information ensures that the specimen can be tracked at every stage from collection to analysis, and any potential tampering can be identified and addressed.
Choice C Reason:
While the physical and mental status of the individual may be noted in medical records or police reports, it is not a standard part of the chain of custody for a blood alcohol test. The chain of custody's purpose is to track the specimen, not the condition of the individual.
Choice D Reason:
The condition of the specimen every hour is not required in the chain of custody documentation. What is necessary is the documentation of any changes in the condition of the specimen that could affect the integrity of the results, such as temperature excursions or signs of tampering.

Correct Answer is A
Explanation
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 D
Explanation
Choice A reason:
Collecting stool directly into a sterile container is not related to providing a sputum specimen. Stool samples are collected for different types of tests, such as fecal occult blood tests or microbiological cultures, and are not used for respiratory assessments.
Choice B reason:
Discarding the first urine of the day and collecting for 24 hours is a procedure for a 24-hour urine collection test, which is used to assess kidney function and other conditions. This process is unrelated to sputum specimen collection, which is used to evaluate respiratory infections or conditions.
Choice C reason:
Aggressively swabbing the inside of the cheek is a method used to collect cells for DNA testing or to check for oral infections. This action does not pertain to sputum collection, which requires a sample from the lower respiratory tract.
Choice D reason:
Taking a deep breath and then expectorating (coughing up and spitting out) is the correct method for providing a sputum specimen. This technique ensures that the sputum comes from deep within the lungs, which is necessary for accurate analysis of respiratory pathogens or cells.
