So I just took my son for blood work. He is 12 months old. He has had a runny nose on and off for his entire life. We checked for allergies. He has none. The doc checked for IGG, IGA, and IGM levels. His IGG is at 450, IGM is at 60 and IGA 10 (this is so low!). Is this an immune deficiency! I am freaking out. Please advise. Also it shows that there are large platelets present and few platelet clumps. Doc said nothing about this. What does this mean. Very worried!!!!
