Fibronectin yo mu mwana uri mu nda (fFN)

Kubyara igihe kitageze ni indwara irangwa no guhagarika gutwita nyuma y'ibyumweru 28 kugeza kuri 37 byo gutwita. Kubyara igihe kitageze ni yo mpamvu ikomeye itera urupfu n'ubumuga ku bana benshi batavukanye umurage. Ibimenyetso byo kubyara igihe kitageze birimo kubyimba kw'inda, impinduka mu miva mu gitsina, kuva amaraso mu gitsina, kubabara umugongo, kubabara mu nda, kumva urimo gukandagira mu kibuno no kuribwa mu nda.

Nk'ishusho ya fibronectin, Fetal Fibronectin (fFN) ni glycoprotein ikomeye ifite uburemere bwa molekile bugera kuri 500KD. Ku bagore batwite bafite ibimenyetso byo kubyara igihe kitageze, niba fFN ari ≥ 50 ng/mL hagati y'umunsi 0 w'ibyumweru 24 n'iminsi 6 y'ibyumweru 34, ibyago byo kubyara igihe kitageze byiyongera mu minsi 7 cyangwa iminsi 14 (kuva umunsi ingero zapimwe mu rurenda rw'inkondo y'umura). Ku bagore batwite badafite ibimenyetso byo kubyara igihe kitageze, niba fFN yiyongereye hagati y'umunsi 0 w'ibyumweru 22 n'iminsi 6 y'ibyumweru 30, hazabaho ibyago byinshi byo kubyara igihe kitageze mu minsi 6 y'ibyumweru 34.
