BMP7-aAB trend over time. The patients that were tested positive for BMP7-aAB showed a transient occurrence of aAB. In most cases BMP7-aAB positivity returned to undetectable levels within two months. In one patient (Patient # 6) a decline was not observed in the samples available for analysis (green). The negative control sera from the same study showed a steady signal at background level (black). BMP7-aAB positive sera (Patients 1–7); BMP7-aAB negative sera (Patients 8–13).
