Question

What are the laboratory tests and diagnostic procedures for Crohn's Disease? Name at least 3 and the results that determine a patient has crohn's disease.

Answer 1

Blood tests may include:

• Antibody tests: These help doctors tell if you have Crohn’s or ulcerative colitis:
  • Anti-Saccharomyces cerevisiae antibody test (ASCA): People with this protein are more likely to have Crohn’s.
  • Perinuclear anti-neutrophil cytoplasmic antibody test (pANCA): People with this protein are more likely to have ulcerative colitis.
• Complete blood count (CBC): It checks for anemia (low numbers of red blood cells) and infection.
• C-reactive  protein: It looks for this protein, which is a sign of inflammation.
• Electrolyte panel: Your body might be low on minerals like potassium if you have Crohn’s-related diarrhea.
• Erythrocyte  sedimentation rate: This gauges the amount of inflammation in your system by measuring the amount of time it takes for your blood to fall to the bottom of a special tube.
• Iron and B12 levels: These can be low if your small intestine isn’t absorbing nutrients like it should.
• Liver function: The disease can affect your liver and bile duct.
