Can a doctor identify if a 19 year old girl is a virgin if so what is name of the test?

They ask: For many societies, the presence of a hymen with a small opening for menstrual blood is the marker for virginity. Bloody drainage with first sex is used as proof. However, some are born without a hymen or one with a thin shelf,neither of which will bleed after sex. In some areas of the world, a surgical procedure rebuilds them. It also does not consider other forms of sex.There is no test.
