Yes, it's on the cross street. Register early, because there are many people. Just register for the internal medicine department on the first floor (but any subject can have a blood test). Register, see a doctor, open a blood test sheet, pay at the payment office (around 20 yuan), take the sheet to the blood test office or call the laboratory, reach in and get the needle, hold the cotton swab to stop bleeding, and wait for ten minutes to get the result.

Don't forget to bring your medical record card, or you'll have to buy it again, which will cost you two yuan more.
