Is Alkaline phosphatase 16 low, normal or dangerous? What does ALP level 16 mean?

📅 Medical Review Date: October 22, 2025

Your Alkaline phosphatase level of 16 is a Low Alkaline phosphatase level.

An alkaline phosphatase level of 16 U/L usually means bone turnover or liver activity is reduced. It suggests possible nutritional deficiencies. Low levels of alkaline phosphatase can cause fatigue, weakness, bone pain, frequent fractures, and poor growth in children. This can be caused by hypophosphatasia, malnutrition, Wilson's disease, or hypothyroidism. Further tests are often needed to identify the cause and guide appropriate treatment.

Low Alkaline phosphatase levels may indicate underlying health problems. The normal range is typically between 30 U/L and 120 U/L. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal Alkaline phosphatase range for men is :30 - 120 U/L
