There are currently no serum levels to help guide appropriate methotrexate therapy. Data from this study will assess the correlation between dosing and whole blood methotrexate(MTX) polyglutamate measurements in children and adolescents with IBD.
This is a cross-sectional study design. Subjects will be requested to provide one blood sample to be collected during the conduct of their routine clinical care. Data related to the diagnosis and interval assessment of enrolled subjects will also be collected.
