Final answer:
Chronic kidney disease (CKD) can affect a complete blood count (CBC) in several ways, including causing anemia and abnormalities in fluid levels, electrolytes, and urine.
Step-by-step explanation:
Chronic kidney disease (CKD) can affect a complete blood count (CBC) in several ways. One common effect is anemia, which is a decrease in the number of red blood cells or hemoglobin levels in the blood. In CKD, the kidneys cannot produce enough erythropoietin, a hormone that stimulates the production of red blood cells. This leads to a decrease in red blood cell count and hemoglobin levels, resulting in anemia. Another effect is abnormal fluid levels in the body, which can impact the composition of the blood and the CBC results. Additionally, CKD can cause deranged acid levels, abnormal levels of potassium, calcium, and phosphate, and hematuria (blood in the urine). These abnormalities can also be reflected in the CBC results.
