Measuring asymmetric dimethylarginine (ADMA) in CKD: a comparison between enzyme-linked immunosorbent assay and liquid chromatography-electrospray tandem mass spectrometry.
Conclusions: In CKD, ELISA overestimates ADMA concentration as compared with LC-MS/MS. Appropriate calibration is needed when ADMA is measured by ELISA in CKD patients.
