一、懷孕之后多(duo)久(jiu)能檢測出來呢

1.早孕試(shi)紙(zhi)檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)時間如(ru)(ru)果(guo)(guo)(guo)使(shi)用早孕試(shi)紙(zhi)來檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)是(shi)否懷(huai)孕,那么可(ke)(ke)以選擇在(zai)月(yue)經推(tui)遲3到5天(tian)后(hou)進行檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)。檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)后(hou),如(ru)(ru)果(guo)(guo)(guo)試(shi)紙(zhi)上顯示為兩條(tiao)紅(hong)杠就(jiu)說明懷(huai)孕,相反情況則就(jiu)表(biao)示沒有懷(huai)孕。2.B超(chao)檢(jian)(jian)(jian)(jian)(jian)(jian)查時間如(ru)(ru)果(guo)(guo)(guo)想通過B超(chao)來檢(jian)(jian)(jian)(jian)(jian)(jian)查是(shi)否懷(huai)孕,可(ke)(ke)以在(zai)月(yue)經推(tui)遲七(qi)(qi)天(tian)后(hou)到醫(yi)(yi)院(yuan)去(qu)做(zuo)B超(chao)檢(jian)(jian)(jian)(jian)(jian)(jian)查。一(yi)般(ban)來說,B超(chao)檢(jian)(jian)(jian)(jian)(jian)(jian)查結(jie)(jie)果(guo)(guo)(guo)的準確性還是(shi)很高的。3.基礎(chu)體(ti)(ti)溫測(ce)(ce)(ce)(ce)試(shi)時間基礎(chu)體(ti)(ti)溫測(ce)(ce)(ce)(ce)試(shi)法(fa)是(shi)在(zai)月(yue)經推(tui)遲后(hou),連(lian)(lian)續每天(tian)測(ce)(ce)(ce)(ce)試(shi)自己的基礎(chu)體(ti)(ti)溫,至少要(yao)測(ce)(ce)(ce)(ce)試(shi)七(qi)(qi)天(tian),如(ru)(ru)果(guo)(guo)(guo)基礎(chu)體(ti)(ti)溫連(lian)(lian)續多天(tian)一(yi)直處于較高的水平,那很可(ke)(ke)能就(jiu)是(shi)懷(huai)孕了。4.血(xue)HCG檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)時間夫妻性生活后(hou)10天(tian)左右(you)即可(ke)(ke)到醫(yi)(yi)院(yuan)進行進行該項檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)來確定自己是(shi)否懷(huai)孕。這個(ge)只要(yao)去(qu)醫(yi)(yi)院(yuan)抽血(xue)就(jiu)可(ke)(ke)以檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)了。這個(ge)方法(fa)也是(shi)很簡單(dan)的,只要(yao)去(qu)正規的醫(yi)(yi)院(yuan)抽血(xue)就(jiu)可(ke)(ke)以檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)(ce)了,一(yi)般(ban)結(jie)(jie)果(guo)(guo)(guo)也是(shi)最(zui)及(ji)時和準確的。

二、早孕(yun)試紙(zhi)檢測懷孕(yun)準確嗎

早(zao)(zao)孕(yun)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)一(yi)般(ban)(ban)在(zai)(zai)同房(fang)后的(de)(de)(de)(de)7-14天就可(ke)初步測(ce)(ce)(ce)(ce)(ce)出(chu)是(shi)否(fou)懷(huai)(huai)孕(yun)。早(zao)(zao)孕(yun)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)是(shi)用于測(ce)(ce)(ce)(ce)(ce)試(shi)(shi)(shi)(shi)(shi)是(shi)否(fou)懷(huai)(huai)孕(yun)的(de)(de)(de)(de)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)。早(zao)(zao)孕(yun)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)測(ce)(ce)(ce)(ce)(ce)懷(huai)(huai)孕(yun)準(zhun)嗎(ma)?雖然早(zao)(zao)孕(yun)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)號(hao)稱(cheng)具有99%的(de)(de)(de)(de)準(zhun)確(que)率,但(dan)實際上早(zao)(zao)孕(yun)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)的(de)(de)(de)(de)正確(que)測(ce)(ce)(ce)(ce)(ce)試(shi)(shi)(shi)(shi)(shi)率差異很大,從50%至(zhi)75%不(bu)等。影(ying)響(xiang)早(zao)(zao)孕(yun)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)準(zhun)確(que)度的(de)(de)(de)(de)因(yin)素主要有以(yi)下幾(ji)種(zhong):1、早(zao)(zao)晨和晚間(jian)做試(shi)(shi)(shi)(shi)(shi)驗可(ke)能(neng)(neng)(neng)對結果有一(yi)定影(ying)響(xiang)。早(zao)(zao)晨的(de)(de)(de)(de)尿液(ye)中一(yi)般(ban)(ban)有最高的(de)(de)(de)(de)HCG值,所以(yi)許多說明書中都建議晨起(qi)的(de)(de)(de)(de)時候(hou)檢測(ce)(ce)(ce)(ce)(ce),但(dan)這也(ye)不(bu)是(shi)絕對的(de)(de)(de)(de)。懷(huai)(huai)孕(yun)時男方超過(guo)55歲(sui)或(huo)(huo)女方超過(guo)35歲(sui)被(bei)稱(cheng)為高齡懷(huai)(huai)孕(yun),懷(huai)(huai)孕(yun)期間(jian)要加(jia)強監護(hu),因(yin)為高齡孕(yun)產婦胎兒畸形的(de)(de)(de)(de)發(fa)生率相對較高。2、檢測(ce)(ce)(ce)(ce)(ce)的(de)(de)(de)(de)時間(jian):HCG一(yi)般(ban)(ban)在(zai)(zai)受精卵著床幾(ji)天后才(cai)出(chu)現在(zai)(zai)尿液(ye)中,而且要達到(dao)一(yi)定量才(cai)能(neng)(neng)(neng)被(bei)檢出(chu)。因(yin)此(ci),對于平時月經(jing)正常(chang)的(de)(de)(de)(de)婦女需在(zai)(zai)月經(jing)推(tui)遲后才(cai)可(ke)能(neng)(neng)(neng)在(zai)(zai)尿中檢測(ce)(ce)(ce)(ce)(ce)出(chu)HCG。而月經(jing)周期長(chang)或(huo)(huo)排卵異常(chang)的(de)(de)(de)(de)婦女需在(zai)(zai)停經(jing)40—44天的(de)(de)(de)(de)時候(hou)才(cai)可(ke)能(neng)(neng)(neng)檢測(ce)(ce)(ce)(ce)(ce)出(chu)。3、尿液(ye)稀(xi)釋(shi):如果喝水過(guo)多使尿液(ye)稀(xi)釋(shi)可(ke)能(neng)(neng)(neng)會(hui)導(dao)致假陰性結果。檢測(ce)(ce)(ce)(ce)(ce)時注意尿液(ye)浸沒試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)的(de)(de)(de)(de)長(chang)度。有時候(hou)尿液(ye)浸沒檢測(ce)(ce)(ce)(ce)(ce)試(shi)(shi)(shi)(shi)(shi)紙(zhi)(zhi)(zhi)的(de)(de)(de)(de)長(chang)度過(guo)長(chang)可(ke)能(neng)(neng)(neng)使測(ce)(ce)(ce)(ce)(ce)試(shi)(shi)(shi)(shi)(shi)結果難以(yi)判斷。

三(san)、早孕試紙什(shen)么時(shi)候(hou)用有效呢

要(yao)知道(dao)早孕(yun)(yun)(yun)試(shi)(shi)紙(zhi)多久(jiu)能驗(yan)出(chu)懷孕(yun)(yun)(yun),就必(bi)須先了(le)(le)解懷孕(yun)(yun)(yun)之(zhi)后(hou)(hou)(hou),多久(jiu)才(cai)(cai)會(hui)產生(sheng)HCG。1、同(tong)(tong)(tong)(tong)房(fang)后(hou)(hou)(hou)等待精(jing)卵(luan)結合時(shi)(shi)間(jian):1-3天(tian)。同(tong)(tong)(tong)(tong)房(fang)之(zhi)后(hou)(hou)(hou),精(jing)子(zi)(zi)(zi)還要(yao)通過一(yi)(yi)段(duan)時(shi)(shi)間(jian)才(cai)(cai)能和卵(luan)子(zi)(zi)(zi)匯合。有時(shi)(shi)候他可(ke)能要(yao)等上(shang)(shang)(shang)72個(ge)小時(shi)(shi),等羞答答的(de)卵(luan)子(zi)(zi)(zi)小姐(jie)成(cheng)熟后(hou)(hou)(hou)出(chu)來(lai)(排卵(luan))才(cai)(cai)能碰上(shang)(shang)(shang)結合。2、受(shou)精(jing)卵(luan)穿過輸卵(luan)管(guan)進(jin)入子(zi)(zi)(zi)宮(gong)(gong)的(de)時(shi)(shi)間(jian):3-4天(tian)。精(jing)卵(luan)成(cheng)功(gong)結合后(hou)(hou)(hou),受(shou)精(jing)卵(luan)一(yi)(yi)邊發育(yu)一(yi)(yi)邊經輸卵(luan)管(guan)向子(zi)(zi)(zi)宮(gong)(gong)方(fang)向移動,大(da)概3-4天(tian)后(hou)(hou)(hou)才(cai)(cai)能到子(zi)(zi)(zi)宮(gong)(gong)。3、受(shou)精(jing)卵(luan)在子(zi)(zi)(zi)宮(gong)(gong)內游(you)蕩(dang)的(de)時(shi)(shi)間(jian):2~3天(tian)。受(shou)精(jing)卵(luan)進(jin)入子(zi)(zi)(zi)宮(gong)(gong)后(hou)(hou)(hou),還要(yao)在里面(mian)游(you)蕩(dang)一(yi)(yi)段(duan)時(shi)(shi)間(jian),才(cai)(cai)能找到落腳點,最(zui)后(hou)(hou)(hou)才(cai)(cai)在子(zi)(zi)(zi)宮(gong)(gong)里面(mian)著床。4.著床之(zhi)后(hou)(hou)(hou),受(shou)精(jing)卵(luan)通過胎盤(pan)和子(zi)(zi)(zi)宮(gong)(gong)相(xiang)連了(le)(le)。胎盤(pan)就會(hui)產生(sheng)HCG。HCG會(hui)出(chu)現(xian)在尿(niao)液里面(mian),但是剛開(kai)始濃度很低,有時(shi)(shi)候早孕(yun)(yun)(yun)試(shi)(shi)紙(zhi)會(hui)驗(yan)不出(chu)來(lai),或者只會(hui)驗(yan)到一(yi)(yi)深一(yi)(yi)淺兩道(dao)杠。其(qi)中淡(dan)的(de)可(ke)能會(hui)非常淡(dan),幾乎看(kan)不出(chu)來(lai)。有人(ren)也稱這個(ge)淡(dan)淡(dan)的(de)杠為“水印”。所以(yi)(yi)(yi)從同(tong)(tong)(tong)(tong)房(fang)到成(cheng)功(gong)著床后(hou)(hou)(hou),才(cai)(cai)能產生(sheng)HCG。而大(da)家可(ke)以(yi)(yi)(yi)把上(shang)(shang)(shang)面(mian)的(de)天(tian)數相(xiang)加一(yi)(yi)下就可(ke)以(yi)(yi)(yi)知道(dao)。同(tong)(tong)(tong)(tong)房(fang)后(hou)(hou)(hou)多久(jiu)可(ke)以(yi)(yi)(yi)驗(yan)出(chu)來(lai)懷孕(yun)(yun)(yun)了(le)(le)。1.如果受(shou)精(jing)早而著床也早的(de)話,最(zui)早同(tong)(tong)(tong)(tong)房(fang)后(hou)(hou)(hou)大(da)概需要(yao)7天(tian)尿(niao)液中才(cai)(cai)會(hui)有HCG,但是這個(ge)時(shi)(shi)候濃度很低,早孕(yun)(yun)(yun)試(shi)(shi)紙(zhi)很難(nan)驗(yan)出(chu)來(lai)。所以(yi)(yi)(yi)至少等2~3天(tian)濃度高一(yi)(yi)點,才(cai)(cai)可(ke)以(yi)(yi)(yi)看(kan)到一(yi)(yi)深一(yi)(yi)淺兩條杠。所以(yi)(yi)(yi)最(zui)早10天(tian)左右早孕(yun)(yun)(yun)試(shi)(shi)紙(zhi)可(ke)以(yi)(yi)(yi)驗(yan)出(chu)懷孕(yun)(yun)(yun)。2.而如果排卵(luan)時(shi)(shi)間(jian)和著床時(shi)(shi)間(jian)都推遲了(le)(le),那(nei)么(me)有些人(ren)可(ke)能要(yao)在15天(tian)左右才(cai)(cai)能測出(chu)懷孕(yun)(yun)(yun)呢。

四、哪些原(yuan)因會導致早孕試紙出現失誤

1、檢(jian)(jian)(jian)測(ce)(ce)的(de)(de)(de)(de)時(shi)間(jian)(jian)。HCG一(yi)(yi)(yi)(yi)般在(zai)(zai)(zai)受(shou)精卵著床幾(ji)天后(hou)才(cai)出現(xian)在(zai)(zai)(zai)尿(niao)(niao)(niao)液(ye)中,而(er)且要達到(dao)一(yi)(yi)(yi)(yi)定量才(cai)能(neng)(neng)被檢(jian)(jian)(jian)出。因(yin)此,對于平時(shi)月(yue)(yue)經(jing)(jing)正(zheng)常的(de)(de)(de)(de)婦女需(xu)在(zai)(zai)(zai)月(yue)(yue)經(jing)(jing)推(tui)遲后(hou)才(cai)可(ke)能(neng)(neng)在(zai)(zai)(zai)尿(niao)(niao)(niao)中檢(jian)(jian)(jian)測(ce)(ce)出HCG。而(er)月(yue)(yue)經(jing)(jing)周(zhou)(zhou)期(qi)長(chang)或排卵異常的(de)(de)(de)(de)婦女需(xu)在(zai)(zai)(zai)停經(jing)(jing)40—44天的(de)(de)(de)(de)時(shi)候才(cai)可(ke)能(neng)(neng)檢(jian)(jian)(jian)測(ce)(ce)出。2、尿(niao)(niao)(niao)液(ye)稀釋。如(ru)(ru)果(guo)(guo)(guo)喝(he)水過(guo)多使(shi)尿(niao)(niao)(niao)液(ye)稀釋可(ke)能(neng)(neng)會導(dao)致假陰性(xing)結(jie)果(guo)(guo)(guo)。3、早(zao)晨(chen)(chen)和(he)晚間(jian)(jian)做試(shi)(shi)(shi)驗(yan)可(ke)能(neng)(neng)對結(jie)果(guo)(guo)(guo)有一(yi)(yi)(yi)(yi)定影響。早(zao)晨(chen)(chen)的(de)(de)(de)(de)尿(niao)(niao)(niao)液(ye)中一(yi)(yi)(yi)(yi)般有最高的(de)(de)(de)(de)HCG值(zhi),所以(yi)(yi)許多說明書中都建議晨(chen)(chen)起的(de)(de)(de)(de)時(shi)候檢(jian)(jian)(jian)測(ce)(ce),但這也(ye)(ye)不(bu)是絕對的(de)(de)(de)(de)。4、檢(jian)(jian)(jian)測(ce)(ce)時(shi)注(zhu)意尿(niao)(niao)(niao)液(ye)浸沒(mei)試(shi)(shi)(shi)紙(zhi)(zhi)(zhi)的(de)(de)(de)(de)長(chang)度。有時(shi)候尿(niao)(niao)(niao)液(ye)浸沒(mei)檢(jian)(jian)(jian)測(ce)(ce)試(shi)(shi)(shi)紙(zhi)(zhi)(zhi)的(de)(de)(de)(de)長(chang)度過(guo)長(chang)可(ke)能(neng)(neng)使(shi)測(ce)(ce)試(shi)(shi)(shi)結(jie)果(guo)(guo)(guo)難以(yi)(yi)判斷。5、不(bu)要在(zai)(zai)(zai)近(jin)期(qi)有過(guo)妊(ren)娠(shen)的(de)(de)(de)(de)情(qing)況(kuang)下憑檢(jian)(jian)(jian)測(ce)(ce)結(jie)果(guo)(guo)(guo)判斷是否懷孕(yun)。因(yin)為(wei)(wei)在(zai)(zai)(zai)終止妊(ren)娠(shen)后(hou)(分娩(mian)后(hou)、自然流(liu)產(chan)和(he)人(ren)工(gong)(gong)流(liu)產(chan)后(hou))的(de)(de)(de)(de)較長(chang)一(yi)(yi)(yi)(yi)段(duan)時(shi)間(jian)(jian)內,HCG可(ke)以(yi)(yi)持續陽(yang)(yang)性(xing)。6、一(yi)(yi)(yi)(yi)些疾病和(he)藥(yao)物可(ke)能(neng)(neng)造(zao)成假陽(yang)(yang)性(xing)結(jie)果(guo)(guo)(guo)。有些腫瘤(liu)細胞(bao)(bao)如(ru)(ru)葡萄胎、絨癌(ai)、支氣管癌(ai)和(he)腎(shen)癌(ai)等,也(ye)(ye)可(ke)分泌HCG。7、不(bu)要使(shi)用(yong)(yong)過(guo)期(qi)的(de)(de)(de)(de)試(shi)(shi)(shi)紙(zhi)(zhi)(zhi)。因(yin)為(wei)(wei)化學試(shi)(shi)(shi)劑(ji)時(shi)間(jian)(jian)長(chang)了(le)會失去效用(yong)(yong),所以(yi)(yi)在(zai)(zai)(zai)購買(mai)時(shi)要注(zhu)意生產(chan)日期(qi)。8、不(bu)要使(shi)用(yong)(yong)已經(jing)(jing)受(shou)潮了(le)的(de)(de)(de)(de)試(shi)(shi)(shi)紙(zhi)(zhi)(zhi)。9、要得到(dao)正(zheng)確結(jie)果(guo)(guo)(guo),最好(hao)是在(zai)(zai)(zai)月(yue)(yue)經(jing)(jing)推(tui)遲兩(liang)周(zhou)(zhou)的(de)(de)(de)(de)時(shi)候再(zai)做早(zao)孕(yun)試(shi)(shi)(shi)紙(zhi)(zhi)(zhi)試(shi)(shi)(shi)驗(yan)。如(ru)(ru)果(guo)(guo)(guo)檢(jian)(jian)(jian)測(ce)(ce)結(jie)果(guo)(guo)(guo)呈陰性(xing),1周(zhou)(zhou)之后(hou)月(yue)(yue)經(jing)(jing)仍未來潮,應(ying)該再(zai)做一(yi)(yi)(yi)(yi)次。在(zai)(zai)(zai)近(jin)期(qi)有過(guo)妊(ren)娠(shen)的(de)(de)(de)(de)情(qing)況(kuang)下其檢(jian)(jian)(jian)測(ce)(ce)結(jie)果(guo)(guo)(guo)不(bu)準,因(yin)為(wei)(wei)在(zai)(zai)(zai)終止妊(ren)娠(shen)后(hou)(分娩(mian)后(hou)、自然流(liu)產(chan)和(he)人(ren)工(gong)(gong)流(liu)產(chan)后(hou))的(de)(de)(de)(de)較長(chang)一(yi)(yi)(yi)(yi)段(duan)時(shi)間(jian)(jian)內,HCG可(ke)以(yi)(yi)持續陽(yang)(yang)性(xing)。一(yi)(yi)(yi)(yi)些疾病和(he)藥(yao)物可(ke)能(neng)(neng)造(zao)成檢(jian)(jian)(jian)測(ce)(ce)結(jie)果(guo)(guo)(guo)假陽(yang)(yang)性(xing),如(ru)(ru)尿(niao)(niao)(niao)中帶血,或服用(yong)(yong)一(yi)(yi)(yi)(yi)些生育藥(yao)品(pin)。有些腫瘤(liu)細胞(bao)(bao)如(ru)(ru)葡萄胎、絨癌(ai)、支氣管癌(ai)和(he)腎(shen)癌(ai)等,也(ye)(ye)可(ke)促進體內分泌HCG。
