Commonly in the arm, to test your blood for hCG.

HCG is a pregnancy hormone that can be detected anywhere from a week to two weeks. 

The results of a urine-based home pregnancy test or a blood-based pregnancy test from your doctor, 

Will based on measurements of this hormone in your urine or blood.

When Should a Blood Test Be Used?

At-home urine tests are more than sufficient and effective in regular pregnancies with healthy women. 

Blood tests are typically utilized in doctors’ offices, 

Especially if there is a probable problem with the pregnancy or any complicating circumstance 

(such as multiples) that necessitates a higher sensitivity blood test.

Blood tests may be requested for high-risk pregnancies, fertility treatments when urine tests are negative but no period has arrived, 

To confirm or rule out a probable miscarriage or multiples, to diagnosis a potential ectopic or tubal pregnancy, 

And for various pregnancy issues.

Urine tests are the standard test for most pregnancies since they are low-cost, painless, 

easy to use, and can be done in the privacy of one’s own home. 

Due to complicating conditions, a pregnancy test is recommended. These tests are also quite accurate, 

Yielding speedy findings that can provide doctors with more information about your pregnancy.

A blood pregnancy test carries relatively little danger. 

Apart from minimal discomfort when the needle is inserted, most people experience no other negative effects from having blood collected. 

Some people may get bruises where the injection was given.

Excessive bleeding, fainting, or infection are all possible side effects of having blood drawn. 

If you’ve ever had trouble getting blood drawn, tell your doctor.

The Results and Their Interpretation:

A normal quantitative hCG blood pregnancy test would reveal that hCG levels rise rapidly throughout the first trimester of pregnancy, 

And then gradually decline after roughly 10 weeks. 

The hCG levels stabilize about 16 weeks and remain stable for the rest of the pregnancy. 

On the other hand, abnormal results can indicate a range of things.

All in all, Most women will be able to confirm pregnancy using a urine-based at-home pregnancy test. A blood test for pregnancy, either qualitative or quantitative, may be required on occasion. Both tests are safe, simple, and accurate for determining whether or not you are pregnant. When anything else is going on, blood tests are the best option.
