Gastrointestinal Health Tests in Puerto Rico

Gastrointestinal health tests are blood tests that check for signs of digestive tract conditions, nutrient absorption problems, or inflammation. They are ordered when a person has ongoing symptoms such as abdominal pain, diarrhea, or unexplained weight loss.

What it measures

Complete Blood Count (CBC) — Checks red and white blood cells; low counts can suggest bleeding or infection in the gut.
C-reactive protein (CRP) — A general marker of inflammation, which may be elevated in digestive tract conditions.
Tissue transglutaminase IgA (tTG-IgA) — Screens for celiac disease, an immune reaction to gluten.
Ferritin and iron — Low levels can indicate iron deficiency, sometimes from chronic gut bleeding.
Vitamin B12 and folate — Low levels may point to poor absorption in the stomach or small intestine.

Who it is for

A primary care clinician or gastroenterologist typically orders these tests for people with persistent digestive symptoms, unintended weight loss, or a known risk of nutrient deficiency.

Preparation

Fasting is often not required, but some labs prefer you avoid food for 8–12 hours if iron or certain other markers are included. Follow your clinician's specific instructions.

Results and what they mean

Results are reported as numbers with reference ranges, and your clinician interprets them alongside your symptoms and history. A single abnormal value does not confirm a diagnosis. This is general information, not medical advice.
