How early can a blood test detect pregnancy before missed period?

 

pregnancy blood test

If you compare a urine test and a blood test, the blood test gives an accurate result, the blood test can take 6 to 12 days, and the urine test takes 6 to 8 days. But if you want an accurate result, the below test can give an accurate result.

 

Blood Tests

Blood tests are of vital importance during pregnancy. Blood will nearly always be taken at intervals throughout pregnancy in order to ensure that it is proceeding normally.


1.Haemoglobin estimation

This estimates the quality and density of red cells in the blood. The normal haemoglobin level in pregnancy is 11–13 g (lower than non-pregnant), and any value less than 11 g is said to be anaemic. If this is so, further blood tests may be done to find out the reason.

 

2.Blood Grouping

People belong to one of four major blood groups. A, B, AB, or O. This knowledge is important not only in case a blood transfusion is necessary at a later stage but also because, in certain cases, incompatibilities between the mother and baby may arise when they have different major blood groups.


3.Viral infection

It is necessary to ascertain the powers of resistance of the mother-to-be to various viruses so that treatment can be instituted in time, if needed. Failure to do so may prove dangerous for the baby.

 

Urine Tests:

These tests are carried out to determine the amounts of sugar and proteins in the urine. The urine is tested for sugar and protein in the urine. The urine is tested for sugar to exclude diabetes and for protein to exclude a urinary infection.

 

Ultrasound scan

An extension of the simple ultrasonic device used for listening to the baby’s heart is the ultrasonic scanner, which uses high-frequency sound waves above those the human ear can detect. It may be used, without harm to the mother or baby, to diagnose a pregnancy as early as 5 or 6 weeks from the last period. In addition, ultrasonic scans are used extensively in the later stages of pregnancy to study the growth of the baby, diagnose twins, and find out to which part of the uterus the placenta has become attached.

If you compare a urine test and a blood test, the blood test gives an accurate result, the blood test can take 6 to 12 days, and the urine test takes 6 to 8 days. But if you want an accurate result, the below test can give an accurate result.

Days Before Missed Period Urine Test Blood Test
6 to 8 days Unlikely Possible
9 to 10 days Possible Likely
11 to 12 days Likely Highly likely
13 to 14 days Very likely Very likely


Conclusion

In my opinion, you can easily find out pregnancy tests using urine and blood tests in the early days. If you have any doubt, you can consult the diagnostic centre. Most women do not get any symptoms in the early days; at that time, you may consult a doctor.
