hCG test: Co to je a kdy ho dělat při těhotenství

When you suspect you might be pregnant, the hCG test, hormonální marker, který tělo začíná produkovat ihned po přivrácení vajíčka k děloze. Also known as beta-hCG, it is the key indicator doctors rely on to confirm pregnancy—long before you even feel any symptoms. This hormone doesn’t appear in your body unless you’re pregnant, which makes the hCG test one of the most accurate tools available.

There are two main types of hCG tests: the urine test you can buy at the pharmacy and the krevní test těhotenství, přesnější metoda, kterou provádí gynekolog a která může odhalit těhotenství už pár dní po oplodnění. While home tests are convenient, a blood test can detect even tiny amounts of hCG and track how quickly the levels rise—something that helps doctors spot potential issues like ectopic pregnancy or early miscarriage. If your hCG levels don’t double every 48–72 hours in early pregnancy, it could signal a problem. That’s why many doctors recommend a blood test if you’ve had previous miscarriages or if your home test is positive but you’re feeling off.

The těhotenství, stav, při kterém se tělo připravuje na vývoj nového života, a hCG je jeho nejprvnější a nejspolehlivější signál usually shows up in your blood about 11 days after conception. That’s why it’s pointless to test too early—even if you feel symptoms like nausea or breast tenderness, waiting until you’ve missed your period gives you the clearest picture. If you get a negative result but still haven’t gotten your period, wait a few days and test again. hCG levels rise fast, but not instantly.

What you won’t find on a home test is the full story. That’s why gynekologs combine hCG results with ultrasound and physical exams. A positive hCG test confirms pregnancy, but an ultrasound at 6–7 weeks is what shows you the heartbeat and rules out a blighted ovum. And if you’re wondering whether your hCG levels are normal—there’s no single number that fits everyone. Levels vary wildly between women, even in healthy pregnancies. What matters is the trend, not the absolute value.

In the posts below, you’ll find real-life answers to questions like: when exactly should you go to the doctor after a positive test? Can hCG be high without being pregnant? How does hCG relate to other prenatal markers like PAPP-A? And what do you do if your test is negative but you still feel different? These aren’t theoretical questions—they’re the ones real women ask every day in clinics across Prague and Brno.
