Final answer:
The phlebotomist reviews the procedure manual before performing a sweat chloride test to ensure accurate specimen handling and patient safety. They must gather the necessary materials such as a test card, serum sample, and reagent, and properly label the specimen.
Step-by-step explanation:
The phlebotomist consults the procedure manual or test guidelines before going to the child's room to perform a sweat chloride test. This manual will provide detailed instructions regarding the test preparations, procedures to be followed, and proper handling of the specimens. It's important for phlebotomists to review the protocol to ensure accuracy in the testing process and safety for the patient.
As outlined in the instructions: the phlebotomist will need to obtain a test card, one patient serum sample, and a bottle of test "reagent". The reagent is often a suspension of horse erythrocytes, and the test card is used to record the results of the test. In addition, the phlebotomist will need to ensure that the specimen is correctly labeled with the patient's name to maintain accurate tracking and identification throughout the process.
Medical technologists or clinical laboratory technologists may analyze the collected sample to diagnose conditions such as cystic fibrosis, where abnormal sweat chloride levels are indicative of the disease.
