In case of delay, the woman seeks to find out as soon as possible if she is expecting a child. A pregnancy test does not always show the correct result. A blood test is much more reliable.
Necessary
- - donate blood from a vein for analysis,
- - wait for the results.
Instructions
Step 1
Wait for the third day of your missed period. To do this, add the average duration of your menstrual cycle to the first day of the last critical days. Add 3 days to the resulting date.
Step 2
Select a laboratory that does the analysis of hCG (human chorionic gonadotropin). Typically, network labs are cheaper and faster than gynecological centers. In addition, you will not be required to refer to an analysis.
Step 3
If you want to know the result as soon as possible, please leave your email address to the administrator of the blood collection center.
Step 4
Be sure to tell your nurse if you are taking hormonal medications.
Step 5
Do the test in the morning on an empty stomach. If you are going to donate blood at other times of the day, do not eat for at least 4 hours before the test. To conduct a study on the level of hCG, blood will be taken from your vein.
Step 6
Wait for the results. Benchmarks in laboratories may differ due to the use of different research methods and mismatched units of measure. Most often, the level of hCG is measured in mU / ml. If your result falls in the 0 to 5 range, you are not pregnant. The hCG level of 25-30000 mU / ml corresponds to 1-4 weeks of pregnancy.
Step 7
You can repeat the analysis in a few days. Until the tenth week of pregnancy, the level of hCG doubles every other day. This indicates that the fetus is developing, the pregnancy is not frozen and not ectopic.
Step 8
Save the test results. You can later show them to your consulting physician. According to the research, the doctor will be able to most accurately determine the duration of pregnancy.
