Ordering Guidance

If there is a known justification for performing both quantitation and antibody levels, this is the correct test to order. If there is not a known reason to perform the antibody levels component, consider ADALX / Adalimumab Quantitative with Reflex to Antibody, Serum. ADALX testing begins with adalimumab quantitation and only performs testing for antibodies when the quantitation results are 8.0 mcg/mL or less.
