ʻO ka Fibronectin Fetal (fFN)

ʻO ka hānau mua ʻana e pili ana i kahi maʻi i hōʻailona ʻia e ka hoʻōki ʻana o ka hāpai ʻana ma hope o 28 a 37 mau pule hāpai. ʻO ka hānau mua ke kumu nui o ka make a me ke kīnā i ka hapa nui o nā pēpē perinatal ʻaʻole i hoʻoilina ʻia. ʻO nā hōʻailona o ka hānau mua ʻana e komo pū me ka ʻūlū ʻana o ka ʻōpū, nā loli i ke kahe ʻana o ka ʻōpū, ke kahe ʻana o ke koko o ka ʻōpū, ka ʻeha hope, ka ʻeha ʻōpū, ka ʻūlū ʻana o ka pelvis a me nā ʻūpā.

Ma ke ʻano he isoform o ka fibronectin, ʻo Fetal Fibronectin (fFN) kahi glycoprotein paʻakikī me ke kaumaha molekala ma kahi o 500KD. No nā wahine hāpai me nā hōʻailona a me nā ʻōuli o ka hānau mua ʻana, inā ʻo fFN ≥ 50 ng/mL ma waena o 0 lā o 24 pule a me 6 lā o 34 pule, piʻi ka pilikia o ka hānau mua ʻana i loko o 7 lā a i ʻole 14 lā (mai ka lā o ka hoʻāʻo ʻana i nā hāpana mai nā mea huna o ka ʻōpū cervical). No nā wahine hāpai me ka ʻole o nā hōʻailona a me nā ʻōuli o ka hānau mua ʻana, inā kiʻekiʻe ka fFN ma waena o 0 lā o 22 pule a me 6 lā o 30 pule, e piʻi aʻe ka pilikia o ka hānau mua ʻana i loko o 6 lā o 34 pule.
