排卵試紙使用的幾個常見疑問

排卵試紙使用的常見疑問（1）——為什么測不到強陽

 
普通的排卵試紙采用上下線比色的方法，當下線近似或明顯深于上線顏色時，表明LH高峰出現(xiàn)了！它固定了一個LH的參照值。這種試紙準確性不高，原因就在于這個參照值的設(shè)定。
 
目前市場上的大部分的排卵試紙是國外的OEM產(chǎn)品，也就是說國內(nèi)的廠商是為國外市場生產(chǎn)的。因此上線的值是根據(jù)歐美人的水平設(shè)在40～50國際單位；而國內(nèi)的女性，她們很大一部分人的峰值是在25～40國際單位，這樣一來，即使排卵正常，下線的顏色也永遠不會深于上線。
 
所以很多姐妹都在問：為什么我總是測不到強陽？
 
如果把參照值定得低一點又怎么樣呢？比如定在25國際單位，這樣一來，很多女性就會出現(xiàn)在很多天都測出了強陽，根本無法判斷哪天是真正的峰值。
 
真是左也難，右也難！
 

排卵試紙使用的常見疑問（2）——LH是怎么波動的

 
姐妹們經(jīng)常提出一個問題：從出現(xiàn)第二條線到強陽大概要多少天？我現(xiàn)在來告訴大家一個經(jīng)過統(tǒng)計出來的一般規(guī)律。育齡女性身體內(nèi)，始終有LH存在，尿中的LH值在0～10之間波動。 隨著卵泡的發(fā)育，到排卵前三四天，LH平均值達到16.5，這時，已經(jīng)可以測到弱陽；到排卵前2天，LH平均值達到26.75；到排卵前1天，LH突然出現(xiàn)高峰，約為59.7；到排卵當天，LH又快速下降至10～25。也就是說LH的高峰實際上只是一個脈沖。
 
有些人，看到剛出現(xiàn)的強陽幾個小時后又不見了，很是疑惑，不知道是怎么回事。其實，這是最正常不過的情況了。在這里，我要說的是：凡是突然出現(xiàn)強陽又突然消失的女性，是激素水平波動非常標準的女性。
 

排卵試紙使用的常見疑問（3）——為什么要扣動扳機

 
卵泡在促卵泡素（FSH）和黃體生成素（LH）的共同作用下，慢慢地發(fā)育成熟。但是，卵泡發(fā)育到什么時候會排出卵巢呢？是誰在控制卵泡破裂和卵巢排出的呢？
 
最主要的控制者就是LH。卵子躺在卵泡里面，就像一顆子彈躺在槍膛里，要讓它發(fā)射出來就要扣動一下板機。而扣扳機是要用力的，這就是一定要出現(xiàn)一個LH脈沖，讓LH出現(xiàn)一個高峰。如果沒有出現(xiàn)LH的脈沖，卵泡會不斷地長大，甚至大到30毫米以上也不排，最后黃素化了。
 
我們使用排卵試紙就是去測有沒有出現(xiàn)一個LH的高峰，也就是有沒有發(fā)生扣動扳機這樣一個動作。
 

排卵試紙使用的常見疑問（4）——扳機扣動了，什么時候發(fā)射

 
如果用排卵試紙測到了強陽，測到了LH的高峰，姐妹們都會很激動，接下來馬上就會問什么時候會真正排卵。
 
借助于大量的統(tǒng)計資料，發(fā)現(xiàn)82.6％的人排卵是發(fā)生在峰值的24小時內(nèi)，17.4％的人排卵是發(fā)生在24～48小時內(nèi)，因此一般的結(jié)論是：排卵發(fā)生在強陽后的48小時內(nèi)。
 
不過你如果真的在強陽后的48小時內(nèi)同房，那肯定是有點晚了，畢竟100人中有83個人是在強陽后24小時內(nèi)排卵的。
 
強陽后24小時內(nèi)排卵其實也太過籠統(tǒng)：1個小時是在24小時以內(nèi)，23個小時也是在24小時以內(nèi)，相差太大了！所以，如果再把這83個人的排卵時間進行統(tǒng)計，那么，相對準確的時間是14.3～19.5小時。這個時間適合大部分人。
 

排卵試紙使用的常見疑問（5）——B超監(jiān)測卵泡，還要用排卵試紙嗎

 
醫(yī)院是很愿意為大家做B超的，B超可以直觀地看到卵泡的大小、形狀，當卵泡發(fā)育到一定大小時，醫(yī)生會建議你們同房，但是會100％成功嗎？也不一定！
 
醫(yī)生看到了卵泡的大小，看到有一顆合適的“子彈”在那里，但是看不到扣動扳機的動作——－個LH的高峰！如果沒有這個高峰，卵泡就不會破裂。沒有LH高峰的卵泡會向兩個方向發(fā)展：一個是繼續(xù)發(fā)展下去，直至黃素化；一個是萎縮變小，最后不見了。
 
我建議姐妹們先用排卵試紙測試，當出現(xiàn)了第二條線后再去做B超，避免過早而不必要的B超，到卵泡發(fā)育成熟時，更應(yīng)該用排卵試紙加緊監(jiān)測這個高峰的出現(xiàn)。
 
雙管齊下，成功的把握就大了！
 

排卵試紙使用的常見疑問（6）——為何會測出異常情況

 
許多姐妹使用了排卵試紙，測到了正確的排卵日而成功了，但是也有些姐妹使用了排卵試紙，非但沒有成功，反而徒增了不少煩惱。
 
有些人強陽連續(xù)測到了3天以上，這樣，就存在兩種可能性，一種是有排卵發(fā)生，它一般發(fā)生在最后一天的強陽以后；另外一種是沒有排卵的持續(xù)高峰。假如在短時間內(nèi)測到了雙高峰，就有黃素化的可能。
 
有的姐妹，從月經(jīng)一結(jié)束就測到了弱陽性，而且這個陽性幾乎沒有什么變化，那么你這個月可能沒有排卵，非但沒有排卵，還可能存在“多囊”了。
 
一旦發(fā)現(xiàn)你使用排卵試紙，出現(xiàn)的現(xiàn)象并不符合一般的規(guī)律，我建議你做這樣的選擇：
 
（1）去醫(yī)院作B超監(jiān)測；
 
（2）使用更科學(xué)的LH半定量檢測試紙，查看到底存在什么問題。
