The CAP Laboratory Accreditation Program is recognized by the federal government as being equal to or more stringent that the government’s own laboratory inspection program. DDC has maintained its accreditation under the CAP program since 2004. In addition to on-site laboratory inspection, CAP accreditation requires laboratories to participate in its Proficiency Testing Program in which CAP sends samples to the lab 3 times a year for DNA testing and evaluates the lab’s results. DDC has participated in the proficiency program since 2004 and has had 100% accuracy with the expected relationship interpretation on all surveys.
(formerly American Association of Blood Banks)
The AABB’s Relationship Testing Accreditation program is the international gold standard for DNA paternity testing laboratories. The program establishes and promotes the highest standards of testing quality and care for patients and clients in all aspects of parentage and other relationship testing. Most courts and other government agencies mandate that DNA tests be performed by AABB-accredited laboratories. DDC received its initial AABB accreditation in 1996 and received AABB’s commendable practice recognition in 2004 for our Dual Process™.
The test evaluates the speed of metabolization of caffeine. The genetic analysis involves the interrogation of the CYP1A gene which encodes the cytochrome P450 protein, which at the liver level is the primary enzyme involved in the metabolism of caffeine. The unfavourable variant of the gene leads to a greater risk of side effects such as nausea, tachycardia, insomnia and hypertension.
The test evaluates the main component of the joints, type 1 collagen. The genetic analysis involves the interrogation of the COL1A1 gene. Reduced production of type 1 collagen leads to less protection from joint injuries.
Exercise has numerous health benefits, but we must be careful of injuries that occur when we do exercises incorrectly. While injuries are always a risk when we do any exercise, some people are more likely to get injured than others and partly due to their genetics. Scientific evidence has shown that some genetic variations can affect the risk of injury. People with a higher risk should adjust their training plan.
Knowing the genetic characteristics that influence an athlete’s physical form is important to discover any predispositions to muscle, tendon and bone injuries. The ability to recover after injury is also influenced by the personal genetic profile. The possible presence of a genetic variant that predisposes to tendon injuries allows us to identify an athlete with a higher than average risk of injury or one who has shorter recovery times, thus preparing the best possible training for each individual.
The test evaluates athletic recovery in relation to anti-inflammatory capacity. The genetic analysis examines the IL-6 gene which codes for the protein of the same name, produced by the muscle during physical activity, with an action to regulate inflammation. The unfavourable variant of the gene leads to reduced control of inflammation and slower recovery after physical effort.
This test analyzes the ACTN3 gene, which determines whether your muscles are more suited for power (fast-twitch fibres) or endurance (slow-twitch fibres) activities.
Power
Power reflects the ability to exert maximum force for a short time.
Those with more fast-twitch fibres have high strength, speed, and explosiveness but tire quickly due to lower oxygen use and faster lactic acid buildup.
Best suited for: short bursts of activity such as sprinting, weightlifting, discus, shot put, and jumping events.
Endurance
Endurance reflects the ability to sustain low-intensity activity over long periods.
Those with more slow-twitch (red) fibres perform better in long-duration exercises, thanks to higher oxygen storage and energy efficiency.
Best suited for: long-distance activities such as marathon running, swimming, cycling, rowing, and cross-country skiing.

Y-STR Male Lineage Testing
Y chromosome testing is ideal for situations when two or more male individuals wish to confirm whether they share the same father or have a common paternal relative. This test, carried out exclusively between males, is a highly accurate and conclusive sibling test.
Who it’s For
If you think two makes are brothers or share the same parent. Confirming relationships with paternal relatives when the alleged father is unavailable, such as a grandfather, uncle, or male cousin.
Gender Restriction:
Only biological males can be tested
If the Y-STR markers are identical, it indicates a shared paternal lineage. Proof Of Paternity offer Y-STR Male Lineage Testing. This type of siblings DNA test is an extremely accurate test and used to determine whether 2 males share a paternal line. Y chromosomes are passed down from fathers to their male children meaning that this chromosome’s inheritance pattern can then be used to trace back the paternal lineage. The conclusive results provided by this test can allow males to determine if they have a shared biological father, grandfather, or male relative
Get the legal documentation you need when the father is unavailable
An avuncular DNA test analyzes the DNA of an aunt or uncle and compares it with a niece or nephew to determine if there’s a biological relationship. Because aunts and uncles share genetic markers with their siblings, comparing these markers can indirectly verify parentage.
The test is normally done when the only means of establishing paternity is by testing the alleged father’s relatives to see whether they are related to the child in question.
The lab cannot perform an avuncular test if the aunt/uncle is NOT a full sibling to the alleged father in question.
Common Uses for Avuncular DNA Tests:
Confirming relationships when parents are unavailable for testing
Clarifying family history or genealogical research
Establishing biological relationships for personal reasons or legal cases
Determine whether or not you are truly related to your sibling. This test is recommended when the alleged siblings are a male and a female who would like to know whether they share one or more common parents. Easy-to-use home kit will get you both the answers whether you share one biological parent, or both biological parents. Or perhaps none? Proof of Paternity offers siblings DNA testing services to help brothers and sisters discover whether they share both biological parents, a single parent or have no parents in common. ; in 5-7 working days; Support at every step of the process.
Common uses cases for this test?
We want to know if we share the same parent.
We think we are brothers, how can we determine our relationship?
This test determines male lineage. Rather than a regular siblings DNA test, a Y chromosome test can be carried out when only males are involved and they wish to discover whether they have the same birth father or different birth fathers. Visit our Y chromosome testing page for more information on this test.
A maternity test determines whether the tested woman is a biological mother of an individual. This is a kind of testing much like paternity testing – but rather than comparing the child’s DNA profile to that of the father, it compares it to their mother. Even when the alleged father’s DNA is not featured, Peace of Mind Paternity’s maternity testing services can still provide conclusive answers, confirming if a child’s DNA does or does not match that of his or her mother.
