Which blood parameter increases with renal failure, arthritis, hypothyroidism, metastatic cancer, alcoholism, or chemotherapy?

• A. Creatinine
• B. Uric Acid
• C. Aldosterone
• D. Lactate Dehydrogenase (LDH)

Answer: (B)

Uric acid is the parameter that rises across these conditions. It is the end product of purine metabolism and is cleared by the kidneys. When renal function is impaired (renal failure), uric acid accumulates because it isn’t excreted efficiently. In cancer, especially with metastasis and during chemotherapy, rapid cell turnover and tumor lysis release large amounts of purines, which are converted to uric acid, pushing levels up. Alcoholism can raise uric acid through increased production and reduced excretion, and hypothyroidism can slow kidney function and uric acid clearance as well. Arthritis in this context refers to gout, a disease driven by elevated uric acid that forms crystals in joints. Together, these scenarios consistently point to elevated uric acid rather than the other options, which are less specifically linked to all these conditions.
