Can I eat breakfast before having blood drawn for HCG and progesterone tests?

Patient's question:

I have an itchy lower body, and my underwear is always yellow. What's going on? Can I eat breakfast before having blood tests for HCG and progesterone?

Doctor's answer:

It is best not to eat, as it may lead to inaccurate test results. Blood tests usually require fasting or not drinking water. Regular follow-up visits to the hospital and adequate rest are recommended. Your condition may be caused by Qi deficiency failing to control blood flow, often resulting from prolonged illness, exhaustion, or spleen deficiency leading to Qi deficiency. When Qi deficiency fails to regulate blood circulation, it causes blood to overflow outside the vessels. Alternatively, chronic blood loss may deplete Qi, turning it into Qi deficiency that cannot hold the blood. It is recommended to use a large dose of Astragalus root decoction to invigorate Qi and stop bleeding.
