How do I read my DNA Sibling Test results report?

Brief introduction

In this article we will present some guidelines that must be taken into account when knowing how to interpret results about DNA tests between alleged siblings or half-siblings.

To be able to identify the results, you need to know a little about it, and to take into account some scientific data, which are not difficult to understand.

Many times, we receive the preliminary report - the results of a DNA test - and we do not know how to recognize the results of it. So, here we bring you a little information about this genetic test, and so that you know how to read the solution of the study that you and your brother have successfully carried out.

Data to interpret a DNA test between siblings

In order to better understand the details of the sibling test results, it is important to emphasize that you are familiar with the terms for proper understanding, and the science behind how a sibling DNA test works.

In this test, our laboratory generates a DNA profile with specific genetic markers (also known as short tandem repeats or STRs) at a set of known locations (loci or singular, locus) in your DNA.

At each DNA locus, you can find 2 genetic variants - known as alleles - which are each inherited, one by the mother and one by the father.3

The laboratory technique that is used to amplify the DNA study is called polymerase chain reaction (PCR). In a sibling DNA test, PCR analysis is used to determine which alleles are specific, which ones they have at each DNA locus, also known as the genetic profile. If two individuals share at least one allele in common, it means that a match already exists.

True siblings or half-siblings need to match on some alleles. This is because siblings don't always inherit the same DNA markers from their parents; Therefore, if this were the opposite case, all the brothers would be practically identical.

or opposite sex are full siblings or half siblings.

Interpreting your results

As soon as you have the report of the results in your hands, here you will find a graph that represents the DNA profiles of each person who has participated in the analysis.

The numbers in the Putative Sibling 1 and Putative Sibling 2 columns are values â€‹â€‹that represent the two alleles that you and your putative sibling received from your parents at the corresponding genetic marker. You can have two identical alleles on a marker (for example the number 14), or you can have two different alleles (for example the numbers 13,14). If the same number is present in both columns, that means you match the corresponding genetic marker of your suspected sibling.

*Full and Half Sisterhood Rate Table*
DNA Locus	Putative Sibling One	Putative Sibling One	Sibling Index (Full)	Sibling Index (Half)
D8S1145	13,14	14	1.32	1.57
D24S54	28,30	28,30	4.25	1.72

The first column, labeled DNA Locus, lists those genetic markers that have been tested for that sibling DNA test (genetic marker example: D8S1145).

The final two columns, both Sib Rate (Full) and Sib Rate (Half), represent the statistical strength of a single match at the corresponding genetic marker. These values â€‹â€‹are calculated based on the type of match, which is normally expected as positive results for true pairs, between full siblings, and both half siblings.

*Sibship Index Table*
Sibship Index	Explanation
0.01	The individuals are 100% more likely not to be true siblings than siblings.
10	The individuals are 10% more likely to be true siblings than not siblings.
100	The individuals are 100% more likely to be true siblings than not siblings.

A higher sibling index (greater than 1.0) corresponds to a higher probability of kinship. The higher that value is above 1.0, the greater the probability that the two individuals are related as true siblings.

half siblings with sibling index results — In this way, you can find out if your alleged brother
is 100 percent compatible with you.

If, on the other hand, a brotherhood index (less than 1.0) corresponds to a lower probability of kinship. The lower this sibling index is less than 1.0, the lower the probability that the two individuals are related as identical blood siblings.

So how do we know if we are half siblings or full siblings?

The division that exists to calculate the percentage of brotherhood that exists between two presumed brothers is the following:

You must divide the Combined Sibship Index divided (full) by the Combined Sibship Index (half).

In such a way, based on an example: if a pair of brothers has a complete brotherhood index of 1.2 and an average brotherhood index of 40, it means that both are 33.3 times more likely to be half brothers than full brothers. (in numeric text mode this is 40 ÷ 1.2 = 33.33 percent chance).

This is how you can calculate and interpret your sibling DNA test results.

I did it from Bermudas! very good service from this company! Thanks!

How it works

Step 1 - Order your kit.
Click ORDER NOW, place your order and you will receive the sample collection kit in a couple of days.
Please contact us at 1-877-219-4485 or WhatsApp +1 647 455 0443 if you are having any troubles ordering.

Step 2 - Take the samples.
Collect the swab samples from the test participants.
Please Watch This Video.

Step 3 - Send the samples to us by mail
Place each pair of swabs in different envelopes (parent / child), then place the two smaller envelopes inside the larger envelope and mail it to the address specified in the instructions.

Step 4 Analysis of your samples in our laboratory

Step 4 - DNA analysis of your saliva samples in our laboratory
Once we receive the samples, we will send you an email to confirm the reception of the samples and proceed to perform the DNA test in our laboratory . You can follow up online at any time using your unique access code to know the progress status of the DNA study.

Step 5 - Receive your results.
Receive your certified results by email, usually about three days, after your samples arrive at the Lab.

I’m very impressed! This company has been nothing but a pleasure to deal with from the moment I picked up the phone. I ordered a paternity kit and it was shipped to me after 3 business days. The test was simple and discreet, very easy to take. The results were available after 5 days and I can finally sleep better knowing the truth.

Everything went smoothly. The kit arrived within 2-3 days and instructions were very easy to follow. Results were sent to me within a week’s time. Customer service was great as I called in to place the order. So happy I know the results now!
