Final answer:
A standard blood test can examine fasted glucose levels, complete blood count, cholesterol levels, and urea levels, which are used to detect diabetes, assess overall health, identify cardiovascular issues, and evaluate kidney function.
Step-by-step explanation:
A standard blood test can examine multiple components and is used for various diagnostics. Answer D is correct: All four of the provided options are correct. A standard blood test can examine:
- Fasted glucose levels; these are used to detect or characterize elevated blood sugar profiles and diabetes.
- Complete Blood Count (CBC); this is used to provide information regarding the overall health of an individual.
- Cholesterol (HDL/LDL) blood levels; used to detect dietary or metabolic issues that promote cardiovascular disease development.
- Urea levels; these can indicate kidney disease or failure.
Specially, the fasted glucose test and the A1C test are integral in diagnosing and managing diabetes, which involves measuring blood glucose levels to assess the function of the endocrine system, particularly the pancreas in producing insulin. Similarly, other conditions like liver or kidney function can also be assessed using specific liver function tests (LFTs) or measures of substances like urea in the blood.
