Which of the following areas should a phlebotomist use for a capillary collection from a 2-month-old infant?

Choice A reason:
Glucose and triglyceride levels are influenced by recent food intake, so it is essential to measure these levels after a period of fasting to obtain accurate results. Fasting ensures that the glucose measurement reflects the body's baseline glucose level without the influence of a recent meal, which is crucial for diagnosing and managing conditions like diabetes. Similarly, triglycerides, which are fats in the blood, can be elevated after eating, so a fasting sample gives a clear picture of the lipid profile for assessing cardiovascular risk.

Choice B reason:
While BUN (Blood Urea Nitrogen) levels can be affected by diet, fasting is not typically required for BUN or alkaline phosphatase tests. These tests are often part of a comprehensive metabolic panel that may or may not require fasting. However, fasting is not specifically necessary for accurate measurement of these two tests.

Choice C reason:
Creatinine and total protein levels are generally not affected by short-term dietary intake, so fasting is not required for these tests. Creatinine is a waste product from muscle metabolism and is used to evaluate kidney function, while total protein levels can indicate a variety of conditions including liver and kidney disorders, but they reflect the body's long-term nutritional status rather than immediate food intake.

Choice D reason:
Lactate dehydrogenase (LDH) and albumin tests do not require fasting. LDH is an enzyme found in almost all body tissues and is released into the bloodstream when tissues are damaged, so its levels are not dependent on food intake. Albumin is the most abundant protein in the blood and is produced by the liver; its levels are used to assess liver and kidney function, nutritional status, and other conditions, but fasting is not necessary for accurate measurement.

Choice A Reason:
A multipart requisition involves multiple copies of a paper form, which can be prone to errors due to manual entry, misplacement, or illegible handwriting. While it provides physical copies for various departments, it is not the most accurate method compared to digital solutions.

Choice B Reason:
A manual requisition is similar to a multipart requisition but typically consists of a single form. It carries the same risks of human error and does not offer the benefits of automated tracking and data entry that come with electronic systems.

Choice C Reason:
An automated requisition is considered the most accurate method for receiving orders for specimen collection. It reduces the risk of human error associated with manual data entry and allows for better tracking and integration with laboratory information systems. Automated systems can also provide immediate feedback if there is an issue with the order, such as a missing patient identifier or a test code.

Choice D Reason:
A verbal requisition is the least reliable method as it depends on the memory and communication skills of the individuals involved. It lacks the documentation and verification steps present in written or automated methods, making it susceptible to misunderstandings and errors.
