Blood tests can provide valuable information and help detect certain stomach problems indirectly by assessing various markers. For example
Complete blood count (CBC): This can indicate infection or inflammation.
Liver function tests: Assess the health of the liver, which is vital for digestion.
Amylase and lipase levels: Elevated in pancreatitis, which affects digestion.
Celiac disease antibody tests: Screen for gluten intolerance.
While blood tests can provide clues, a definitive diagnosis often requires a combination of tests, including imaging and endoscopic procedures, for a comprehensive assessment of gastrointestinal health.
