Understanding Lab Tests for Malabsorption Disorders
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Malabsorption disorders are conditions where the intestines cannot properly absorb nutrients, vitamins, or minerals from food. These disorders, including celiac disease, Crohn's disease, and pancreatic insufficiency, can lead to nutritional deficiencies even when adequate nutrition is consumed.
Recommended Test
Folate (Folic Acid)
This test measures folate levels in the blood, which can be significantly reduced in malabsorption disorders. Conditions such as celiac disease or Crohn's disease commonly affect the body's ability to absorb folate from food, making this test a valuable indicator of intestinal absorption problems and helping to guide both diagnosis and nutritional management.

How Blood Tests Help Diagnose Malabsorption
While there isn't a single blood test that directly diagnoses all malabsorption disorders, blood testing is fundamental for identifying the condition by measuring specific nutrients and vitamins in the bloodstream. Low levels of certain nutrients can indicate that the intestines are not absorbing them properly, even when dietary intake is adequate.
Key Diagnostic Marker
Testing for specific vitamin and nutrient levels helps healthcare providers identify malabsorption patterns and determine appropriate treatment strategies to prevent serious complications from nutritional deficiencies.
Understanding Your Results
Low folate levels, especially when combined with adequate dietary intake, may suggest malabsorption. Your healthcare provider will interpret results in the context of your symptoms and may recommend additional testing to confirm the underlying cause and develop an appropriate treatment plan.
Important Considerations
