📌 What is the ALP Test?
A blood test that measures alkaline phosphatase (ALP), an enzyme found in the liver, bones, kidneys, and intestines. It helps detect liver disease, bone disorders, and bile duct issues.
📊 Normal Ranges (may vary by lab)
✔ Adults: 44 - 147 U/L
✔ Children & Adolescents: Higher levels due to bone growth
✔ Pregnancy: Increased ALP levels are normal
🚨 High ALP Levels May Indicate:
🔺 Liver disease (hepatitis, cirrhosis, bile duct obstruction)
🔺 Bone disorders (Paget’s disease, osteomalacia, rickets)
🔺 Gallbladder disease (gallstones, bile duct blockage)
🔺 Certain cancers (bone tumors, liver metastases)
📉 Low ALP Levels May Indicate:
🔻 Nutritional deficiencies (zinc, magnesium)
🔻 Hypophosphatasia (rare bone disorder)
🔻 Malnutrition
🎯 Purpose of the Test
✅ Evaluates liver function and detects bile duct blockages
✅ Diagnoses bone diseases and conditions affecting bone metabolism
✅ Monitors liver and bone disease progression or treatment
✅ Assesses vitamin D and mineral deficiencies
💡 Key Facts
🔹 ALP is higher in children and pregnant women due to bone growth and placenta production
🔹 Liver and bone-specific ALP tests (isoenzyme analysis) help pinpoint the source of high ALP
🔹 Additional tests (bilirubin, ALT, AST, GGT) may be ordered for a full liver function assessment
🔹 Fasting before the test may be required for accurate results
