What pregnancy tests detect h hcg?

Congratulations, you’re pregnant! Now it’s time to start thinking about prenatal care and all the fun things that come along with growing a tiny human. But before you dive into baby name books and stock up on onesies, you’ll need to confirm your pregnancy with a pregnancy test.

Pregnancy tests work by detecting the presence of hCG (human chorionic gonadotropin), a hormone produced by the placenta after an egg has been fertilized. There are many different types of pregnancy tests available, but they all work in slightly different ways to detect hCG.

So what exactly do pregnancy tests detect when it comes to hCG? Let’s investigate.

The Basics: What is hCG?

Before we dive into how pregnancy tests detect hCG, let’s first talk about what hCG actually is. Human chorionic gonadotropin is a hormone that is produced by the placenta after implantation occurs in early pregnancy. The purpose of this hormone is to communicate with the ovaries and prevent them from ovulating again during the course of the pregnancy.

A woman’s body typically starts producing small amounts of hCG within 24 hours after conception occurs. As time goes on and her body adjusts to being pregnant, levels increase dramatically until they peak around week 10-12 gestation. After that point, levels gradually decline until birth.

Different Types of Pregnancy Tests

Now that we know what exactly this magical ‘hcg’ thingy does (it does lots basically)let us look at various ways in which one can verify whether they are pregnant or not depending on their budget:

Urine-Based Home Pregnancy Tests

These are cheap yet accurate home-based kits used for confirming if expecting mothers have high volumes of HcG or non-existent volume thereof according for specific weeks since sex occurred or last menstruation date.(Bummer)

Blood-Based Pregnancy Tests

These are more accurate and confirm if there is any HcG existing in the blood samples from an expecting mother. Interestingly, plasma tests can detect much lower amounts of hCG than urine tests – this makes them perfect for use within days after conception.

How Do Pregnancy Tests Detect hCG?

Pregnancy tests work by detecting the presence of hCG in either a woman’s urine or her blood (Depending on one’s budget really). There are two main types of pregnancy tests: over-the-counter home-based kits and medical-grade tests done by doctors at their clinics using blood samples.

Urine-Based Home Pregnancy Tests

Home kits used to test for pregnacny usually detect whether there is high levels human chorionic gonadotropin which usually spikes up depending on how long since last ovulation occurred.Launching with phrase from above:

What happens when you use a pregnancy kit with your urine (weird right)

When you use a home-based kit that detects hcg, what you’re actually doing is analyzing your own urine to see if any hcg exists. This works because if you’re pregnant, your body starts producing hCG shortly after the fertilized egg implants into the uterine wall. As more time passes — about 48 hours later) amount produced increases.

Most over-the-counter pregnancy kits require dipping a test stick into collected fresh first-morning/mid-streamedurine then waiting few minutes before reading off results..

The test stick contains antibodies that will alert users through coloring changes should they have higher volume of hCg present based on estimated weeks/days from sex/last menstruation date utilized as index (instructions given henceforth)

Special Note: If results appear ‘faint’, it implies low concentration of HcG but does not definitely mean negativeSo yes fuzzy maybe kinda result isn’t just limited to reports and results..not even tests conducted on pee ..but we can handle it.

Blood-Based Pregnancy Tests

When corroborating with a lab technician/doctor at their facility, blood samples are acquired from expecting mothers so that they may be run through proprietary analysis mechanisms. This discerns whether hCG exists in the collected fluids.

Quantitative Blood Test

This test is usually done for medical purposes as It confirms amount of HcG in your plasma not to mention tracking its volume over time…should you need that kind of monitoring (Note: Incomprehensible for me too)

And now, brace yourself:

There’s actually nothing much else I can say about this particular test except lay it bare and capitalise (LITERALLY) hard-to-pronounce technical jargon trying to explain obscure biological processes occuring within somebody’s plasm

  • Reaginic Antibody Flocculation Test
  • Trophoblastic Tumor Markers (Subunit Beta)
  • Radioimmunoassay Technique .

Ok we’re done!

Qualitative Blood Test

So back to conventional stuff, A qualitative blood test leaves no one either ‘in’ or ‘out’, but rather is used just to confirm existence of HcG chunks floating loosely around in your plasma.All decisions based upon ‘positivity’ shall henceforth rely upon ultrasound flashes; or other forms of ocular proof.

Special Note: These tests work best when analyzed backwards from the end result — what does having high levels of hCG mean? The answer is pregnancy! So if you have high levels detected, congratulations are very likely in order!

When Can You Take a Pregnancy Test?

One common question people have about taking pregnancy tests is when exactly can you take them? Well, it depends on which type of test you’re taking – home-based urine kits versus medically-led blood samples really do effect datewise variables involved in our verification process.

Home Pregnancy Tests

Most over-the-counter (OTC) pregnancy tests recommend waiting to take the test until the first day of your missed period. This is because by this point, a positive result is more likely to be accurate since hCG levels should have been high enough in both blood and urine samples for detection.

However! Some newer tests are advertising as “6 days before your missed period”, “10 days after ovulation” or similar tags which indicate sensitivity even earlier on.

But please do note: since we are all unique variables some of us might show detectable signs awhile after several other mothers/takers..so one shouldn’t start selling baby items based on confident self-vision put up counter-date-quick assessments.

Blood-Based Pregnancy Tests

Blood-based pregancy confirmations generally may detect HCG at 7-12 post-conception days whereas Urine tset can only consider themselves reliable from weeks afterward.The best approach here really would be to follow results given by a specialty medical practitioner who has expertise in the field -they would know what’s best for you!(not Google!)

Special Note: While it can be tempting to try and take a pregnancy test early, keep in mind that doing so may result in false negatives due to low hCG levels. Be patient — it’s better than worrying over bloating kid-names just because you took an early home-test.(rolling my eyes)

In Conclusion

So there you have it folks: A guide through subjective getting pregnant mystery.Lots happens during conception; not just squirting semen into nothingness! Do Wait till at least 1 cycle passes when not monitored medically before trying out confirmation kits.It is advisable although not mandatory depending on availability/desire/terror within.Take deep breaths…do prenatal yoga (whatever helps really) and if anything seems off consult someone with actual expertise (this article notwithstanding) . Good luck and happy baby-making!
