Negative blood pregnancy test, A urine sample is used in one type of pregnancy test, while a blood sample is used in the other. The presence of a hormone called human chorionic gonadotropin is detected in both pregnancy tests (hCG). The placenta produces this hormone shortly after the embryo attaches to the uterine lining, and it rapidly accumulates in your body during the first few days of pregnancy. The majority of your pregnancy symptoms are caused by this rapid shift in hormones, which may also cause negative blood pregnancy test results.

The difference between hCG blood tests and hCG urine tests that you may buy over the counter is significant.
Dehydration and the time of day you test can affect the findings of urine tests, however,
An hCG blood test can yield definitive results even when hCG levels are very low.

What is the procedure for taking an hCG blood test?
The quantitative test determines the amount of hCG hormone in a sample of blood.
Following these steps, a healthcare worker draws a blood sample:
To block the flow of blood and make the veins in your arm more apparent,
An elastic band is put around your upper arm. This makes it easy to insert the needle.
A vein is discovered, and the skin surrounding it is cleansed with alcohol.
The needle is placed into the vein, and the blood is collected through a tube connected to the needle’s end.
The elastic band is removed from your arm once enough blood has been collected.
Cotton or gauze is applied to the puncture site while the needle is withdrawn.
The cotton or gauze is pressed against the skin and fastened with a bandage.
You may feel a brief stinging or pinching sensation when the needle is placed, or you may not feel anything at all.
You may experience moderate pain or stinging while the needle is in the vein.
You can feel some slight pain at the puncture site thereafter.
The findings of your hCG levels being tested in a blood sample are submitted to your doctor.
They may schedule a meeting with you to discuss the test findings.

Is it true that the hCG blood test is always correct?
There is no such thing as a test that is 100 percent correct every time.
The hCG test can provide both false-negative and false-positive pregnancy findings.
If you have any doubts about your results, your doctor will assist you in deciphering them or will order more testing.
Certain drugs, especially those containing hCG, might affect the findings of an hCG blood test.
Fertility medications like Profasi, Pregnyl, and Pergonal are among them.
High hCG levels can also be caused by using marijuana.
The existence of germ cell tumors can also affect test findings.
Germ cell tumors are frequently seen in the reproductive organs and can be malignant or benign.
These tumors develop in the same cells that produce your eggs or sperm.
In the absence of pregnancy, a high hCG level caused by a negative blood pregnancy test may suggest that your doctor has to do more tests to determine whether cancer is a problem.
Related: Home pregnancy test negative and late period
To sum up, However, hCG can be present in several non-pregnant circumstances, leading to a false-positive hCG pregnancy test, If a test results in a false-positive result, it means that a woman is pregnant when she isn’t.
