Alpha-fetoprotein (AFP) - fetal kumuʻiʻo reproducible ake a me gastrointestinal nā loko o ka fetus, i mea maʻamau a noho i loko o ke koko a me ka amniotic loli o ka hapai wahine. High a haahaa pae o AFP i e pili me kekahi hanau mā, e like me Edwards maʻi pale, Down maʻi pale, anencephaly, spina bifida, a pela aku. E kuhikuhi i hiki deviations i loko o ka ulu ana o ka fetus, e ho'āʻo AFP.

He aha ka ka AFP hōʻike?

I ka wā mai 15th i 20th pule o ka hāpai keiki, hapai na wahine he nui loa e paipai, e lawe mai invasive prenatalʻike, a pinepine haawi mai ia i ka kŰia. Kekahi o ka loa benign ki ina hana like i e ole koi i na anal, o ka AFP hoao ana, a hoʻoholo i ka AFP i hāpai keiki i loko o ke koko o ka makuahine, o ka. E lawe i ke koko, mai na aa koko o ka makuahine, a hoouna aku la ia i ke keʻena hoʻokolohua no Ka Ikepili. I ka hopena o ia, e like me ka rula, ka mea, uaʻikeʻia ma hope o 1-2 pule, ua hoohalikeia me ka makahiki o ka makuahine, a me kona lāhui kāʻei kua, e loiloi i ka likelihood o Loaʻaʻia aaiaoe kāna hana.

Ka loa pololei nā hoailona o kēia hōʻike, oia he 16 i ka 18 no ka hebedoma. Aie i ka mea i ka AFP i hāpai keiki alters kona kiʻekiʻe o ka lehulehu no ka oi ike loea ana hualoaʻa pono i kūlike loa ka lā o ka hapai ana. Eia naʻe, ua pono hoike aku i ka manao ana o ka hoao ana hualoaʻa mea i kaʻike,, akā, wale wehewehe i ka pono hou lapaʻau 'e huai ae congenital malformations i loko o ka fetus.

ʻO wai ka mea pono i ka AFP hōʻike?

O ka holo ana, ia mea pono e hapai na wahine a pau i mālama 'ia i ka like ana manaʻo. Naʻe, i loko o ka OAXA AFP i hāpai keiki Pono e e hooponoponoia ia mea, no ka wahine i:

• i ka ohana mōʻaukala o nā mā ka hanau ana;
• mua o 35 makahiki;
• i likeʻole lapaʻauʻia paha ai 'i hāpai keiki;
• i mimikō.

Inā AFP ua kiʻekiʻe, ka mea e hōʻike i ka ulu pēpē i ka neural şarkı kina e like me spina bifida a anencephaly, hakuʻala a me urinary'āpana abnormalities a me nā hānau mā. Ka nui kiʻekiʻe o AFP i kekahi paipai congenital esophageal mā. Naʻe, i ka loa e like me ka kumu o ke kiekie AFP pae mea paʻewa ai ka launa pū o ka hāpai keiki.

Inā ka AFP i hāpai keiki ua undervalued, a ma laila nō'āno'ē pae o hCG a me estriol, kēia e hōʻike ana i ka ulu fetus i e ulu retardation, trisomy 18 (Edwards maʻi pale), trisomy 21 (Down maʻi pale) a me nā 'ano o ka chromosomal abnormalities.

Ia nā mea AFP ikea ai

He nui no ka hoomanao i ka AFP hoao ana - ia mea,ʻaʻole he PalekanaEND_LINK hōʻike, ka mea wale memo i ke ola o ka fetus mea ma kamepiula. Ma ka hihia o'āno'ē pae o Alpha-fetoprotein kauoha hou ikea ai no ka pololeiʻike. A oi makeʻe kulana kokoke mea e paa i ka lua AFP ho'āʻo ai 3D-ultrasound. Inā retesting keʻae i ka AFP i hāpai keiki (maʻamau AFP pōpilikia like me ka hana ana o gestational makahiki) overstated paha understated i häʻawi mai ai iä oi invasive ke kaʻina hana e like me amniocentesis.

I loko nō o ka mea i ua ole lawe i ka Alpha-fetoprotein ikea mai no a pau hapai wahine, i kekahi hihia i mea e pono ai. A, i ka hou ana i ka discomfort o ka unuhi aku la ia i ke koko, aohe mea i ka pilikia a me kaʻaoʻao mau waiwai pili me kona manaʻo. 'O kēia ka mea mau hoao ana e hua ole pū i na anal, a no ia mea, mai ho oweliweli i ka pilikia a hiki i ka makuahine a me ka bebe. Inā ka hoao ana ua i kaumaha aku ai, o ka wahine ia iho ke koi aku ma luna o kona ana (ke ole, o ka papa, i manaoio aku i ka mea hiki e pono no ia ia a me kona pēpē), e hoʻopaʻa i ka maʻamau papa o ka hāpai keiki.
