The creatinine clearance test measures how well your kidneys filter waste from your blood. It evaluates kidney function by comparing creatinine levels in your blood and urine over a 24-hour period. Creatinine is a waste product produced by muscles and excreted by the kidneys. A creatinine clearance test helps diagnose kidney diseases or monitor kidney function, especially in individuals with chronic kidney disease or at risk due to diabetes, hypertension, or other conditions. It provides a more accurate picture of kidney function than blood tests alone.

ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are key liver enzymes measured in blood tests to assess liver function. ALT is primarily found in the liver and indicates liver cell damage, while AST is found in various organs, including the liver, heart, and muscles. Elevated levels of either enzyme can suggest liver injury or disease, but ALT is more liver-specific. Both tests are essential in diagnosing conditions like hepatitis, fatty liver disease, or liver damage caused by alcohol or medications. Doctors use these results together to provide a clearer picture of liver health.

What is a Phosphate Blood Test and Why Is It Important?A phosphate blood test measures the level of phosphate in your blood, a mineral crucial for bone health. Phosphate plays a vital role in building strong bones and teeth, helping the body store and use energy, and supporting muscle and nerve function. Abnormal phosphate levels can indicate conditions such as bone disorders, kidney disease, or problems with calcium regulation. This test helps doctors assess overall bone health and identify imbalances that could lead to bone weakness or other health concerns.

What to Expect from a Testosterone Test?A testosterone test measures the level of testosterone, a key hormone in both men and women, but especially important for male sexual development and health. During the test, a healthcare provider draws blood from a vein, usually from your arm. This is a simple procedure that typically takes a few minutes. The results help diagnose conditions like hypogonadism (low testosterone), infertility, or hormonal imbalances. Normal levels vary by age and sex, so understanding your results in context is essential for proper diagnosis.
