Attention:
1, do not eat, drink, or smoke for at least 30 minutes before swabbing.
2, incorrect collection will result in bad data and re-collection
3, do not put two individuals’ collected swabs into one specimen envelope. Mixed swabs cause contamination and result in re-collection

2, Wash and dry you hand
3, Peel and take out the cheek swab from a package. Do not touch the swab head.
4, Rotate and scrape inside of one cheek for 30 seconds with one swab. Put the 1st swab into the specimen envelop directly. Rotate and scrape inside of another cheek for 30 seconds with another swab. Put the 2nd swab into the specimen envelop directly also, discard original swab package.
5, Let the swabs dry inside the specimen envelope at room temperature for 30 minutes, then seal the specimen envelope
6, Return the specimen envelope with swabs back to our Sample Receiving Center.

Understand your DNA Test Report
Paternity 'NOT EXCLUDED'
It means that alleged father is most likely to be the father of the child. The tested data in the table strongly support a father-child relationship. When conclusion: paternity NOT EXCLUDED is made, the Combined Paternity Index (CPI) is 100 (or larger) and the Probability of Paternity is typically 99.99% (or higher).
​
Paternity 'EXCLUDED'
It means that alleged father is not the biological father of the child because the data in the table do not support a father-child relationship. Whenever alleged father is EXCLUDED as the biological father, the Combined Paternity Index (CPI) is 0 and the Probability of Paternity is 0%.
​
Sibling DNA Test:
An important point: sibling DNA test is less conclusive than paternity or maternity test unless one parent joins the test. Sibling DNA test can’t confirm or disprove that two people are full or half siblings with 100% certainty, since two siblings could share 0% or 100% of their DNA theoretically.
​
Full siblings:
97% of biological full siblings had a full sibling kinship index value of 10 or greater
98% of unrelated individuals had a full sibling kinship index value of 0.1 or less
Half siblings:
65% of biological half siblings had a half sibling kinship index value of 10 or greater
76% of unrelated individuals had a half sibling kinship index value of 0.1 or less
​
Grandparent Grandchild Test, Aunt/Uncle Nephew/Niece Test and Cousin DNA Test:
Kinship index value is >10, support for relationship
Kinship index value is < 0.1, no support for relationship
Kinship index value is between 0.1 and 10, inconclusive for relationship

6, Gently place the lancet on the side of selected finger of another hand
7, To activate the lancet, press lancet firmly on the side of selected finger. Do not remove the lancet until you have heard a 'click'. Set the lancet aside.
8, Drop the blood on the 1st blood card. Then, move your finger to another blood card to drop blood on it.
9, After completed, place a sterile your against bleeding area to until bleeding stops and replace with a bandage.
