What does a blood chemistry panel typically measure?

A blood chemistry panel is a comprehensive laboratory test that evaluates various substances in the blood to assess a person's overall health and detect a range of medical conditions. This panel typically measures important biomolecules such as glucose, which is crucial for energy metabolism; electrolytes, which are vital for maintaining fluid balance and proper muscle and nerve function; and markers of kidney function, such as creatinine and blood urea nitrogen (BUN), which help in evaluating how well the kidneys are filtering waste from the blood. Additionally, liver enzymes, like alanine aminotransferase (ALT) and aspartate aminotransferase (AST), are included to assess liver health and function.

The other options provided are not representative of what a blood chemistry panel measures. For instance, measuring bacteria and viral loads pertains more to microbiological testing rather than a standard chemistry panel. Similarly, heart rate and blood pressure are vital signs measured through a physical examination rather than through a biochemical test like a blood chemistry panel. Lastly, collecting patient weight and height is part of a physical assessment but not related to the biochemical composition of the blood. Thus, the selection encompasses the relevant measurements expected from a blood chemistry panel.
