Lab tests

Lab tests are a snapshot of where you are today, and not a long-term view of your health.

It is important to understand that lab test results will change over time, reflecting your condition. Lab tests that your physician may order on a regular basis will include the following:





White blood count

Normal value: 4.5-11.0 th/cmm


Male Hematocrit (HCT): 41%-53%

(Female) Hematocrit (HCT): 36%-44%


Normal value: under 8.0 mg/L


Less than 10


The normal range is 3.5 to 5.5 g/dL or 35-55 g/liter

Stool culture

identifies infection – such as a stool test called Clostridium difficile

Stool Calprotectin - Stool markers or stool biomarkers

The most common cut-off value recommended by the test manufacturers is 50 micrograms/g.  

Liver Enzymes

Variable range


  • Blood count (CBC): Identifies anemia, infection, inflammation, and monitors certain medications.
  • Hematocrit: Male Hematocrit (HCT): 41%-53%

 (Female) Hematocrit (HCT): 36%-44%

  • CRP: C-reactive protein, which is a marker of inflammation.
  • ESR: Erythrocyte Sedimentation Rate: Identifies inflammation-reactive protein - identifies inflammation.
  • Albumin: Measures levels of a specific group of proteins.
  • Electrolytes: Checks for dehydration and medication side effects.
  • Stool markers and cultures: Identifies inflammation and infectious complications.
  • Stool Calprotectin: Can suggest inflammation or infection in the intestines.
  • Liver enzymes: Screens for liver complications.


Liver Panel: A liver panel may be used to screen for liver damage, especially if someone has a condition or is taking a medication that may affect the liver.  Commonly used tests to check liver function are the alanine transaminase (ALT), asparate aminotransferase (AST), alkaline phosphatase (ALP), albumin.
