Today's tests still work by measuring HCG.

今天孕检依旧通检测 HCG 进行。

If there's no HCG, the wave of urine and enzymes just passes on by.

如果没有 HCG，尿液和酶 就去了。

Okay. Um..." Are my HCG levels doubling every 48 hours? "

还有… … “我促性腺激素每48小时就翻一番吗？”

For instance, false negatives can occur if concentrations of HCG aren't high enough for detection.

比如说，错误阴性反应可能会发生如果 HCG 没有足够多以至能被检测出来。

When the wave hits the first zone, the reaction zone, Y-shaped proteins called antibodies will grab onto any HCG.

当它到达反应区，Y 字形状蛋白质也就是抗体会抓住任何识别到 HCG。

As the pregnancy progresses, HCG supports the formation of the placenta, which transfers nutrients from mother to fetus.

随着怀孕程，HCG 能够帮助形成胎盘，胎盘能够将母亲体内营养物质传送给胎儿。

These changes can worsen morning sickness, which is caused in part by the hormone HCG — and can also happen at other times of day.

些变化会加剧晨间孕吐，一部分是由 HCG 激素引起——也可能发生在一天中其他时间。

They use tiny strips of fabric infused with antibodies that detect the HCG hormone and basically have taken the guesswork out of everything.

他们将可检测 HCG 激素抗体注入小型纺织条内，基本能保证准确性。

Monoclonal antibodies on the pregnancy test stick bind to the HCG hormone found in the urine of pregnant women causing a colour change.

验孕棒克隆抗体与孕妇尿液中发现 HCG 激素结合，导致颜色变化。

Secured to this zone are more Y-shaped antibodies that will also stick to HCG on one of its five binding sites.

个区域有更多 Y 字抗体，在它五个面都会黏住 HCG。

These changes can worsen morning sickness, which is caused in part by hormone HCG— and can also happen at other times of day.

些变化会加重孕吐，部分是由激素 HCG 引起，也可能在一天中其他时间发生。

Particular types of functional cysts are those associated with PCOS, which happen because of chronic anovulation, and theca-lutein cysts, which are only seen during pregnancy, when there's too much HCG.

PCOS可导致特征性功能性囊肿，由长期无排卵导致；卵泡膜黄素囊肿只见于怀孕期间，由HCG分泌多导致。

The doctors are also looking for HCG, but with tests that are more sensitive and quantitative, which means they can determine the exact level of HCG in your blood.

医生也在寻找 HCG，但是医生用测试会更加敏锐和量化，他们能够判定你血液中HCG 准确水平。

The HCG in the pregnancy urine triggers what's known as Corpora Hemorrhagica, a temporary growth on the rabbits ovaries easily spotted by prodding doctors within 48 hours of pee injection.

妊娠尿液中 HCG 会引发人们所知黄体出血。是一种在尿液注射后48小时内，助产医生很容易发现兔子卵巢中暂时性生长现象。

HCG is produced in the earliest stages of pregnancy and starts a game of telephone that tells the body not to shed the inner lining of the uterus that month.

孕早期人体会产生 HCG，随后开始了电话游戏，告诉身体那个月不要出子宫内薄膜。

The HCG in the pregnancy urine triggers what's known as Corpora Hemorrhagica, a temporary growth on the rabbits ovaries easily spotted by product doctors within 48 hours of pee injection.

怀孕尿液中 HCG 会引发所谓出血性体液，是兔子卵巢一种临时生长物， 在注射小便后 48 小时内产品医生很容易发现。

If HCG is present, it gets sandwiched between the AB1 enzyme and AB2, and sticks to the test zone, allowing the attached dye-activating enzyme to do its job and create a visible pattern.

如果有 HCG，它会被夹在AB1 酶和 AB2 酶之间，然后黏在测试区，让附带着染色激活酶发挥作用创造一个可视图案。

Theca lutein cysts are more likely to develop when there's more hCG than usual, like when there are multiple fetuses, or with gestational trophoblastic disease, where tumours made up of placental cells causes higher than normal hCG levels.

卵泡膜黄素囊肿一般发生于hCG较正常高情况，如多胎妊娠或患有妊娠滋养细胞疾病时；该病中由胎盘细胞组成肿瘤会导致hCG较高。

They began to notice a pattern of fluctuations throughout a woman's 28 day menstrual cycle and saw a sharp spike in the level of HCG (human chorionic gonadotropin) in pregnant women, and nowhere else.

他们开始注意到女性28天月经周期中有一种波动模式，孕妇 HCG（人绒毛膜促性腺激素）水平急剧升，而其他人则不会。

Today's tests still work by measuring HCG. But, throughout the 20th century, other methods were explored; the AZ Pregnancy Reaction Test popped up in 1928 and was the first of several " bioassays" or animal-based tests.

今天测试仍然通测量 HCG 起作用。 但是，在整个 20 世纪，人们探索了其他方法；AZ 妊娠反应测试于 1928 年出现， 是多项“生物测定” 或基于动物测试中第一项。
