Which test is NOT related to electrolyte levels?

Total Protein (TP) is the correct answer because it measures the total amount of protein in the blood, which includes albumin and globulins. This test is primarily used to assess nutritional status, liver function, and certain diseases related to protein synthesis and breakdown.

In contrast, both potassium and sodium are directly related to electrolyte levels in the body. They play vital roles in maintaining fluid balance, nerve function, and muscle contraction. Uric acid, while often associated with conditions like gout, is not classified as an electrolyte. Nonetheless, it is still connected to metabolic processes in the body rather than the regulation of electrolytes. Therefore, total protein stands out as the test that does not assess electrolyte levels.
