SELDI profile showed a peak with average mass of 9099-regulated in NTDs compared with control urine.

Abstract

<p>Urine mass spectra of 2 mothers with NTD-affected fetuses were compared with those of 2 control mothers and the mass-to-change ratio (m/z) ranged between 8800–9400 Da. X-axis showed molecular weight of peaks and Y-axis showed intensity of peaks.</p
