There are a number of drug testing methods that can detect d-amphetamine. These include the following:

• Blood test 
• Urine test

• Hair follicle test

Vyvanse drug test detection time

• How long does Vyvanse stay in the urine

It can be detected in the urine for up to three days after ingestion. A fresh urine sample is collected and check for the presence of amphetamine. Vyvanse remains longer in the urine if the person has been using it for a long period of time and if the urine pH is alkaline. ^{(4, 5)}

• How long does Vyvanse stay in your hair

The hair follicle has the longest window of detection. A hair sample is collected to check for the presence of amphetamine. It would take a week or two for the amphetamine to be detected in the hair. The good news is that it can detect Vyvanse metabolite for up to three months post ingestion. ^{(5, 6)}

• How long does Vyvanse stay in your saliva

This drug test used a high-performance liquid chromatography, which provides a quick turnaround of only 15 minutes. However, it can only detect Vyvanse metabolite for up to 2 days post ingestion.

• How long does Vyvanse stay in the blood

It can detect Vyvanse for up to 24 hours post ingestion. However, this method of drug testing is rarely used because of the slim window of detection and invasive nature. It is also more expensive than urine testing. ^{(6, 7)}

How to pass a drug test for Vyvanse?

A urine test is one of the commonly used drug testing methods. If you have been taking Vyvanse for therapeutic reasons, then you will most likely test positive for Vyvanse metabolite. You just need to bring the prescription medication to the drug testing officer to inform him that your doctor prescribes it for some reasons.

On the other hand, if you have been dependent or abusing Vyvanse, you can somehow get rid of it from your system by drinking plenty of water. This promotes urination, which will eventually flush out Vyvanse metabolites from your system.

You should also exercise as sweating is another way of removing toxins from the body. ^{(2, 4, 5, and 7)}
