greetings. This mild, isolated elevation indicates a low-grade inflammatory process rather than a severe, acute bacterial infection. Potential causes include a recovering or low-grade viral infection, early or atypical inflammatory bowel conditions, or localized subclinical tissue inflammation. To narrow this down, three distinct possibilities to consider are a lingering viral gastroenteritis, an early systemic inflammatory condition, or a low-grade food-related sensitivity or intolerance. Appropriate options for investigation or management involve serial clinical monitoring by his pediatrician, keeping a detailed pediatric food and symptom log, or pursuing targeted secondary evaluations such as a fecal calprotectin test or repeat inflammatory tracking

Kindly consult once for discussion

Take consultation because detail information needed.. Question need to know-1)How is weight of baby in last 1-2 month Gain/Loss..2) why crp repeated on 29 may after 4th may level(due to persistent Abdominal pain or any other issues)..3) any specific food item causing it..4)how is oral food intake?

Mild Elevated CRP is may be because of Viral infection

Whats the duration of pain abdomen? Any associated complains like fever, vomiting, jaundice? Any history of constipation? What was the reason for such an extensive workup if there was no complain other than pain abdomen.Mild crp elevation can be some viral illnes or early bacterial infection or some inflammatory process.
