Unfortunately, it’s not possible to make changes to an order afterwards because a referral is created upon completing the purchase on Vitals’ website. If you want to add any tests, you can place a new order, but this will generate multiple referrals. It’s important to inform the staff at the laboratory that additional referrals should be tested. If you want to make a return to place a new order, you can contact customer service at: kundservice@vital.se.
