Overview

Laboratory findings consistent with the diagnosis of prostate cancer include elevated serum prostate-specific antigen level, low red blood cell count, elevated blood urea nitrogen, and elevated serum creatinine. Some patients may have elevated concentration of serum calcium and alkaline phosphatase, which is usually suggestive of bone metastases.

Laboratory findings

Laboratory findings consistent with the diagnosis of prostate cancer include:

• Elevated serum prostate-specific antigen (PSA) level
• Low red blood cell count
• Blood chemistry tests

• Elevated blood urea nitrogen (BUN)
• Elevated serum creatinine
• Elevated alkaline phosphatase

• It may indicate that prostate cancer has spread to the bone.

• Elevated calcium

• It may indicate that prostate cancer has spread to the bone.
