The first breathalyzer test was invented in 1954 by Robert Borkenstein, a police officer in the United States. His device allowed for the quick and non-invasive testing of a person's blood alcohol content through their breath.
In Schmerber v. California, the Supreme Court held that the warrantless blood test was allowed due to the exigent circumstances of alcohol metabolizing in the blood. The court balanced the suspect's Fourth Amendment rights against the need for accurate blood alcohol evidence in DUI cases.
Assuming you mean Blood Alcohol Content (BAC) the court (or police department) has two main ways. The first is the breathalyzer test, which involves blowing into a tube while a computer analyzes the amount of alcohol on your breath. The second (and most accurate) method is through a blood test where the actual BAC is measured by using blood taken from your body.
Marijuana can typically be detected in urine for up to 30 days, and in blood for a shorter period of time. After 90 days, it is unlikely that marijuana would still be detectable in either urine or blood.
The VA perk test is typically valid for one year, after which it may need to be renewed. It is important to check with the specific VA office or department for any updates or changes to the validity period of the test.

Having a blood test before you are married is usually a good idea, even if it isn't required. However, that is to make sure neither of the partners have any STDs or other diseases. If a mother has negative blood of any type and the father has a positive they will need to test the baby's blood type (before it is born). If it is positive the mother will need to receive a shot in order to reduce the risk of miscarriage.
The only blood test that you need is to test the HCG hormone. But you can ask your doctor to do a blood test for you and they will know which one to do! If not then i would see a different doctor :)
