Urine and serum concentrations of Cytokeratin 19 in preeclampsia

Serum levels of Cytokeratin 19 fragment are increased in women with preeclampsia. However this does not result in a significant difference in CYFRA 21-1 levels in maternal urine. Thus Cytokeratin 19 fragment may prove to be a valuable biomarker for preeclampsia in serum but not urine. We propose further longitudinal studies to investigate the role of Cytokeratin 19 in maternal serum of women with preeclampsia.
