Alkaline Phosphatase
ALP is an enzyme indicating liver, bile duct, and bone health, with elevated levels suggesting liver or bone disorders.

Understanding Your Results (U/L)
Low
(< 30 U/L)
Low ALP levels can be associated with malnutrition, certain genetic disorders, or hypophosphatasia, a rare bone disorder. Symptoms of low ALP levels may include weakness, fatigue, bone pain, and frequent fractures. Addressing the underlying cause, such as improving nutritional intake or managing genetic conditions, is essential to restore normal ALP levels and prevent complications.
Optimal
(30 - 110 U/L)
Normal ALP levels indicate healthy liver function, proper bile duct function, and normal bone metabolism. This balance suggests effective enzyme activity and overall good health, reflecting the absence of liver, bile duct, or bone disorders.
ALP levels near the upper limit may suggest mild liver or bone stress. This can be due to factors such as recent mild liver or bone activity, certain medications, or age-related changes. Monitoring these levels and addressing any contributing factors can help maintain balanced ALP levels.
ALP levels near the lower end of the reference range are generally not a cause for concern and indicate normal enzyme activity. This suggests that the liver, bile ducts, and bones are functioning properly.
High
(> 110 U/L)
Elevated ALP levels can indicate liver diseases such as hepatitis, cirrhosis, or bile duct obstruction (e.g., gallstones). It can also suggest bone disorders like Paget's disease, osteomalacia, or bone tumors. Symptoms may include jaundice, fatigue, abdominal pain, bone pain, and fractures. Identifying and treating the underlying cause is crucial for managing high ALP levels and preventing further complications.
