Final answer:
A phlebotomist must use an alcohol-free antiseptic, such as benzalkonium chloride or iodine, for a BAL test to ensure the results are valid in a court setting. Adherence to protocol and proper use of disinfectant solutions are critical to maintaining the integrity of the sample.
Step-by-step explanation:
A phlebotomist must use a specific type of cleanser for a Blood Alcohol Level (BAL) test to ensure the results are admissible in court. This cleanser is typically an antiseptic that does not contain alcohol, such as benzalkonium chloride or iodine, to avoid contaminating the sample with additional alcohol. The correct use of this cleanser is crucial as the BAL test results could have legal implications. To perform a BAL test accurately, the phlebotomist should follow the appropriate protocol which includes sterilizing the area where blood will be drawn using the correct cleanser.
In clinical settings, disinfectant solution efficacy can be determined by using a type of test that challenges the disinfectant with test "reagent" or organisms to ensure proper usage. Phlebotomists, who are often certified by organizations such as the American Society of Phlebotomy Technicians, are trained in collecting blood through venipunctures, capillary sticks, and arterial sticks. After the blood is collected, it may be analyzed for various purposes, including BAL tests that are typically conducted by medical technologists or clinical laboratory technologists. Ensuring the integrity of the sample with the appropriate cleanser is key for the test's credibility.
