Hi there, I'm mom to Jake a very loving little 4yr old. Jake has had health issues since birth. A skin biopsy revealed Mastocytosis at age 9mo,asthma,gerd,sleep apnea,severe restless leg syndrome, disaccharide malabsorption, vit d def, and anemic. Poor growth, and belly pain and diarrhea daily. Positive blood in stool, positive lactoferrin, negative for infection or parasites, colonoscopy and endoscopy scheduled for June 10.. Any thoughts? Looking for answers, does positive lactoferrin always indicate IBD??
