Additional information
The sibling DNA test compares the DNA of two individuals to assess the probability that they share one or both biological parents. The result is expressed as a statistical probability, ranging from nearly 0% to 99.99%, reflecting the strength of the relationship. Contrary to the simplified idea that “full siblings” always share exactly 50% of their DNA (or 25% for half-siblings), these numbers are only averages. Each genetic relationship is unique, and the exact proportion of shared DNA can vary from one case to another. This is why our laboratory analyzes profiles across 22 distinct loci and uses a likelihood ratio calculation to provide a clear and precise probability estimate.

Questions?
What is the difference between a twin test and a sibling test?
A twin test determines whether twins are monozygotic (identical) or dizygotic (fraternal) by comparing their DNA.
A sibling test, on the other hand, evaluates the biological relationship between two individuals to determine if they are brothers or sisters by analyzing the proportion of shared DNA.
The time required to process and analyze your sample depends on the type of report you have ordered. Once it arrives at the laboratory, processing times are as follows:

Our tests fall into several categories:
The information extracted from the tests and presented in our reports should be considered as indications of predisposition and not as definitive diagnoses. Their relevance may vary according to numerous environmental factors.
Yes, for relationship tests, our partner laboratory can perform the analysis on non-standard samples such as a toothbrush or blood, for example. The cost is higher, ranging from $750 to $850, and the turnaround time is longer because the laboratory first applies a DNA extraction method tailored to the type of material. Some samples (e.g., hair without roots, old tissues, cigarette butts that are too old) contain very little or degraded DNA.
Here is the exhaustive list of possible sample types and their acceptability criteria:
