## Overview

The Sibling DNA Testing Kit offers a highly accurate 18 loci genetic test that allows you to determine siblingship from the comfort of your home. With results delivered via email in just 5 business days, this kit includes all necessary materials for easy sample collection and guarantees confidentiality with discreet packaging.

## Description

The DNA collected with this kit, when processed by the laboratory, will confirm whether you and another individual share a biological parent (usually the father). The USD270 laboratory fee will be payable when samples are returned for testing. This sibling DNA test offers absolute peace of mind with accurate results available within 5 working days of receipt of samples. We test 18 loci to ensure the highest level of accuracy. With easy-to-follow instructions, samples can be collected at home and returned to us to test two siblings. The sample collection kit contains 4 x sterile mouth swabs (2 swabs for each participant), welcome letter, step-by-step sample collection instructions, client registration form, consent form and return envelope. The kit is sent in plain packaging for absolute confidentiality and discretion. Instructions Collect cheek cells by rolling the tip of the sample collection swab firmly on the inside of the right cheek and under the tongue for about 30 seconds. Be certain to move the swab over the entire inner cheek surface. This action should be firm but not aggressive and should not be uncomfortable. Light pressure is adequate. This procedure is totally painless, even for young babies and children. Repeat this process for the same individual with the second swab. Repeat the process for both individuals being tested using a different set of swabs and envelope for each person. Finally, place all of the swab envelopes, plus the completed consent form, into the return envelope. Then simply return to us.
