A complete blood count (CBC) test doesn't directly assess kidney function. However, certain CBC results, along with other tests, can provide indirect clues about kidney health. For example, a low CBC level can indicate reduced kidney function.
Here's why:
- Red blood cell count: A low red blood cell count (anemia) can occur due to kidney failure, as the kidneys produce erythropoietin, a hormone that stimulates red blood cell production.
- White blood cell count: Elevated white blood cell counts can suggest infection or inflammation, which can impact kidney function.
- Platelet count: Abnormal platelet counts may indicate a broader health issue, potentially impacting the kidneys.
It's crucial to remember that a CBC test alone is not sufficient to diagnose kidney problems. Additional tests, such as creatinine levels and urinalysis, are necessary for a comprehensive evaluation of kidney function.
