Crohn's Disease (CD) Test in Puerto Rico

The Crohn's Disease (CD) Test is a blood test that looks for certain markers that may be linked to inflammation in the body. It is not a definitive test for Crohn's disease but can help a doctor decide if more testing is needed when someone has symptoms like ongoing diarrhea, belly pain, or weight loss.

What it measures

C-reactive protein (CRP) — A protein that rises when there is inflammation somewhere in the body.
Erythrocyte sedimentation rate (ESR) — A test that shows how quickly red blood cells settle; a faster rate can mean inflammation.
Complete blood count (CBC) — Checks for low red blood cells (anemia) or high white blood cells, which can happen with inflammation or infection.
Fecal calprotectin — Although this test uses a stool sample, it is often ordered alongside blood tests to check for inflammation in the intestines.

Who it is for

A primary care doctor or a gastroenterologist (a doctor who treats digestive system conditions) typically orders this test when a person has symptoms that could be due to Crohn's disease or another inflammatory bowel condition.

Preparation

No special preparation is usually needed for the blood test. You can eat and drink normally unless your doctor gives you other instructions.

Results and what they mean

Results are reported as numbers for each marker, often with a reference range. Your doctor will interpret these results along with your symptoms, physical exam, and other tests to decide what they mean for you. This information is not medical advice; only a qualified healthcare professional can diagnose or treat any condition.

Frequently asked questions

Can this test tell me for sure if I have Crohn's disease?

No. This blood test can show signs of inflammation, but it cannot confirm Crohn's disease. Your doctor may need other tests, such as a colonoscopy, to make a diagnosis.

What if my results are normal?

Normal results do not rule out Crohn's disease. Some people with Crohn's disease may have normal blood test results, especially if the disease is mild or not active.

What if my results are abnormal?

Abnormal results mean there is inflammation somewhere in your body, but it does not necessarily mean you have Crohn's disease. Many conditions can cause inflammation. Your doctor will consider your symptoms and may order more tests.

Is this test covered by insurance?

Coverage varies by insurance plan. Check with your insurance company or the lab to find out what your plan covers.
