What's this test for?

This test is ideal if you've had blood work showing high alkaline phosphatase levels and your doctor needs to find out where it's coming from. Elevated alkaline phosphatase can signal liver problems, bone disorders, or other conditions, but this test pinpoints the specific source by identifying which organs are producing the enzyme. It helps guide your doctor toward the right diagnosis and treatment plan when something is causing your alkaline phosphatase to be abnormally high.

What happens after I get my results?

You'll receive doctor notes in simple language explaining which isoenzyme types were elevated and what that means for your liver, bone, or other organ health. These notes include personalized recommendations about which specialist to see, what additional tests might be needed, and lifestyle factors to consider based on your results. You'll also get the standard lab report and can track your isoenzyme levels over time using our trends feature, which is especially helpful for monitoring chronic liver or bone conditions.

What's included in this test?

This panel measures Alkaline Phosphatase, Bone Isoenzymes, Liver Isoenzymes, Intestinal Isoenzymes, and Placental Isoenzymes. By identifying which tissue is producing elevated alkaline phosphatase, your doctor can distinguish between bone disorders like Paget's disease or fractures, liver conditions such as hepatitis or bile duct obstruction, intestinal issues, or pregnancy-related changes. This detailed breakdown provides crucial diagnostic information that a total alkaline phosphatase test alone cannot reveal.

How should I prepare for this test?

No fasting is needed for this test, which makes it convenient and easy to schedule. You can eat and drink normally before your blood draw. However, it's always a good idea to inform your healthcare provider about any medications or supplements you're taking, as some can affect enzyme levels.

Who should consider getting this test?

This test is recommended for anyone whose routine blood work has shown elevated alkaline phosphatase levels. It's particularly useful for people experiencing unexplained bone pain, liver symptoms like jaundice or abdominal discomfort, or those with known bone or liver conditions that need monitoring. Your doctor may order this test to differentiate between liver disease, bone disorders, or other causes of elevated alkaline phosphatase.

What symptoms indicate I may need this test?

You may need this test if you're experiencing symptoms like persistent bone pain, unexplained fractures, yellowing of the skin or eyes, abdominal pain, fatigue, or abnormal liver function. It's also indicated if routine blood work shows high alkaline phosphatase without a clear cause. This test helps your doctor determine whether your symptoms are related to liver, bone, or other organ issues.

What is alkaline phosphatase and why does it matter?

Alkaline phosphatase is an enzyme found in several body tissues, including liver, bones, intestines, and kidneys. When your total alkaline phosphatase is high, it signals that something may be wrong, but doesn't tell you where the problem is. The isoenzyme test breaks down the total into specific types from different organs, allowing your doctor to pinpoint whether the elevation is coming from your liver, bones, or elsewhere, which is crucial for proper diagnosis and treatment.

What does high bone isoenzyme mean?

High bone isoenzyme levels indicate increased bone activity, which can occur with bone growth in children and adolescents, bone healing after fractures, or bone diseases like Paget's disease, osteomalacia, or bone metastases. If you're an adult with elevated bone isoenzymes, your doctor will likely investigate further to rule out bone disorders or abnormal bone remodeling. This helps distinguish bone-related causes from liver problems when total alkaline phosphatase is elevated.

What does high liver isoenzyme mean?

Elevated liver isoenzyme suggests a liver or bile duct problem, such as hepatitis, cirrhosis, bile duct obstruction, or fatty liver disease. This finding helps your doctor focus on your liver health and may prompt additional liver function tests or imaging studies. High liver isoenzyme levels can also occur with certain medications or alcohol use, so your doctor will consider your complete medical history when interpreting results.

How often should I retest my alkaline phosphatase isoenzymes?

Retesting frequency depends on your diagnosis and treatment plan. If you're being monitored for a known liver or bone condition, your doctor may order this test every few months to track disease progression or treatment response. For one-time diagnostic purposes to identify the source of elevated alkaline phosphatase, you may not need retesting once the cause is identified and addressed. Your healthcare provider will determine the appropriate follow-up schedule based on your specific situation.
