High ALP on Your Blood Test? What Alkaline Phosphatase Really Means

If your ALP (alkaline phosphatase) level came back high or low on your blood test, you may be wondering what that result actually means. In this video, we explain how doctors interpret ALP results and why this enzyme can become elevated or decreased in the blood. ALP is produced in several organs, but most of the ALP circulating in the blood comes from the liver and bones. Understanding where ALP comes from can help determine whether an abnormal result may be related to liver disease, bile duct problems, bone activity, medications, or other conditions. You’ll learn: • What alkaline phosphatase (ALP) is • Why ALP levels become elevated • When high ALP may be related to liver disease or bile duct obstruction • Why bone growth, vitamin D deficiency, or fracture healing can raise ALP • How doctors determine whether ALP comes from the liver or the bones • What mild, moderate, and very high ALP levels may indicate • Possible causes of low ALP levels We also discuss how additional tests such as GGT and 5-nucleotidase help physicians determine the source of elevated ALP. If you recently received blood work and noticed that your ALP result was outside the normal range, this video will help you understand the most common reasons why this happens and when further evaluation may be needed: https://youtu.be/_AO8Qq3nGyY
