What Does the ALT Blood Test Measure?The ALT (alanine aminotransferase) blood test measures the levels of ALT enzyme in your blood. ALT is primarily found in the liver and plays a role in converting proteins into energy. Elevated ALT levels can indicate liver damage or disease, as the enzyme is released into the bloodstream when liver cells are damaged. Conditions such as hepatitis, fatty liver disease, or alcohol-related liver injury often cause elevated ALT levels. Regular monitoring helps assess liver health and guide necessary interventions.

What Does the eGFR Blood Test Measure?The eGFR (estimated Glomerular Filtration Rate) blood test is a key indicator of kidney function. It measures how well your kidneys filter waste from your blood. A lower eGFR suggests impaired kidney function, while a higher eGFR indicates normal kidney health. This test helps detect early signs of kidney disease and assess its severity. Regular monitoring of eGFR is crucial for people with chronic conditions like diabetes or hypertension, which can affect kidney function.

What Does the ACR Blood Test Measure?The ACR (Albumin-to-Creatinine Ratio) blood test evaluates kidney function by measuring the amount of albumin (a protein) in the urine compared to creatinine. It helps detect early signs of kidney damage, particularly in people with diabetes or high blood pressure. A higher-than-normal ACR indicates potential kidney damage, which could lead to chronic kidney disease (CKD) if untreated. Early detection allows for better management to slow down or prevent progression of kidney damage.

What Does Serum Alkaline Phosphatase Measure?Serum alkaline phosphatase (ALP) is an enzyme found mainly in the liver, bones, and bile ducts. A blood test measuring ALP levels helps assess liver function and bone health. Elevated levels can indicate liver damage, bile duct obstruction, or bone diseases like osteoporosis or Paget’s disease. Low levels may be linked to malnutrition or certain genetic conditions. Interpreting ALP results provides valuable insight into overall health and can guide further diagnostic testing.
