I spoke with Cincinnati Immunology lab, and they said you’re welcome to email one of their doctors and they would recommend which tests to order through them.
She said either doctor would be good to contact, that they would be helpful:
Dear Dr. Marsh and Dr. Blessing,
I have a 15 year old patient, David Noah Kittle-Pals who presents with reoccurring upper respiratory and skin infections, without a fever or elevated white cell blood count, who was put on prophylactic antibiotics but has had 5+ breakthrough infections over the past year.
I would love to hear your recommendations regarding further testing at your facility which might provide insight into this case.
We recently discovered David had an abnormal result to his CD 19 level, and we believe this may be a clue to the root of his deficiency.
David’s mother, Tara Kittle, has an extensive history of infections, polyps, and autoimmune disorders dating back to childhood, including a positive blood culture (corney bacterium and endercococcus) with a wcb of 6.7 and absence of fever.
There’s also an extended family history of David’s maternal grandfather, great-grandfather, and great-great grandmother of deaths from cancer and long history of infections. (Throat, colon and leukemia).
Dr. Lauren Crosby
