Before ordering

Here’s how it works:

  1. Choose a laboratory package: Simply select one of our pre-designed laboratory packages and place your order on the website. When ordering a laboratory package on, you choose which laboratory you want to visit for your sample collection. Each collection point indicates which laboratory they use. You can also order individual tests. You can find all our laboratory packages here.
  2. Visit a laboratory and take your blood sample: You can then go and have your blood sample taken at your convenience. Most of our sampling locations offer drop-in services, but in some cases, you may need to contact them to make an appointment. You can find all our laboratories here.

Anyone who is over 18 years old, has a Swedish personal identity number, and a BankID can order a test.

The order must always be filled in with the details of the person to be tested. If you want to order tests as a gift for someone else, gift cards are available. The gift card is used in Vital’s online store, and the person who gets the gift can choose which test package they want to order.

You cannot visit a sampling location directly. First, you need to place an order with the gift card here on so that a referral is created. You have to choose a laboratory package from Vital’s website and add it to the shopping cart. The code is entered under ‘discount code/gift card,’ and the amount is deducted from the total.

Vital is not a publicly funded service, so exemption cards are not valid.

It’s up to individual employers to determine what they consider as wellness activities. In Epassi, Vital cannot be included as it’s a VAT-exempt service.

All of Vital’s services are exempt from VAT.
