Before taking tests for pregnant women for the amount of hCG, the following preparation is required:
• Fasting for 7–8 hours before the procedure;
• Limit intake of any liquid several hours before the examination.
It is also necessary to warn your doctor about taking medications.
Statistics show that the highest concentration of hCG in the blood is observed in the first half of the day, so the doctor usually prescribes such a test in the morning.
If the recommendations are not followed, the study may show an unreliable result, so additional procedures will have to be performed.
