How pregnancy test works
The quantity of HCG hormone in a pregnancy test is measured. During pregnancy, HCG levels rise.
Because it is generated by the cells that create the placenta and supply food to the growing fetus,
HCG is known as the pregnancy hormone.
When a fertilized egg attaches itself to the uterine lining, it is discharged.
Around 10 to 14 days after pregnancy, HCG can be detected in the blood and urine.
It reaches its climax between 8 and 11 weeks of pregnancy.
A level of less than 5 mIU/ml indicates a negative HCG result (milli-international units per milliliter).
HCG levels greater than or equal to 25 mIU/ml are considered positive for pregnancy.

At-home urine testing
The urine is placed on a chemical strip in a home test.
The result is ready in 1 to 2 minutes, however, the time varies depending on the brand of test.
The person collects urine in a container and either dips the pregnancy test stick into it,
Or drops the sample onto the test strip using an eyedropper.
A pregnancy stick can also be inserted into the urine stream.
Because each brand of testing has its unique method of delivering data,
It’s critical to read the package insert to learn how to interpret the results.
The result may take the form of a change in color, a change in a marked line, or the display of a symbol,
Such as a plus or minus, or a response in a test window,
Or such as the words “pregnant” or “not pregnant” depending on the test.

Blood pregnancy testing
A quantitative and qualitative HCG test are two approaches to screen for pregnancy using blood.
A quantitative blood test determines how much HCG is present in the blood.
A qualitative test determines whether or not HCG is present.
There are certain advantages to blood testing.
It is capable of detecting early pregnancy and measuring HCG levels.
It is, however, more costly, takes longer to get results, and must be done in a medical office.

When to take it?
A home urine test can be taken as soon as 14 days after suspected conception,
But waiting until a missed period will provide a more trustworthy result.
Some market testing can be completed early. This is dependent on their sensitivity.
It’s crucial to read the box insert to figure out what the best and earliest times are to take the exam.
The optimum time to take a urine pregnancy test is right after you wake up in the morning.
This is because even if the lady is pregnant,
Drinking a lot of liquids before taking the test might result in a false negative.
