Our Tests

Testing: Child and alleged father samples

Establishes the paternal link between an alleged father and a child, without the need to test the mother. This level of DNA test offers peace of mind and can be conducted solely by the applicant at home. These DNA tests are 100% conclusive for exclusion and greater than 99.9% for inclusion.

Testing: Child, mother and alleged father samples

Establishes unquestionably the paternal link between an alleged father and a child by testing the mother's DNA as well. This level of DNA test offers peace of mind and can be conducted solely by the applicant at home. These DNA tests are 100% conclusive for exclusion and inclusion.

Testing: Child and alleged mother samples

Establishes unquestionably the maternal link between an alleged mother and a child. This level of DNA test offers peace of mind and can be conducted solely by the applicant at home. These DNA tests are 100% conclusive for exclusion and greater than 99.9% for inclusion.

Testing: Second relationship, e.g. additional child, alleged father or other participant

If more than one relationship needs to be established. Provided at a reduced cost for subsequent tests. Please note that costs for an additional applicant vary for the X-SV Female Lineage Test, X-Chromosome Test and Non-Invasive Prenatal Paternity Test.

Testing: Two alleged siblings

This DNA test determines the statistical probability of whether siblings (brothers and sisters) share the same two parents or not. The relationship between alleged siblings (full or half) can be established with 15% exclusion and 90% inclusion conclusivity.

When the issue of siblingship is in question, the recommended method to determine whether individuals are true biological siblings is to test their parents. In situations where the alleged parents are unavailable for testing, a siblingship DNA test can be performed to analyze the relationship of biological siblings. Including one common parent greatly increases the accuracy of this type of DNA analysis and is recommended if at all possible (at extra cost). If this is not possible, disclosing that siblings share a common mother or father can also lead to more meaningful results.

IMPORTANT NOTE: When testing male siblings to determine whether or not they share a common father, a Y-STR Male Lineage DNA Test may provide a more conclusive result. If siblings are trying to determine whether or not they share the same maternal lineage, an X-SV DNA Test may provide a more conclusive result. Please contact us for more information.

Testing:Two males

Y-STR Male Lineage Paternity TestThe Y-STR male lineage DNA test is used to determine whether two or more males are related through their paternal lineage. The Y chromosome is passed from father to son and has a relatively infrequent mutation rate, thus it remains the same through many generations.

This DNA test focuses on the Y chromosome and results in a unique Y-STR profile for each male tested. It is important to note that this DNA test will not differentiate between men that are in the same paternal lineage.

For example, if a male child "A" and his alleged half brother Child "B" (Child "B" having a different mother than Child "A") want to know if they have the same biological father, and they have the same Y-STR DNA profile, it is practically proven that they share the same father. If the profiles do not match, then they do not share the same biological father.

This is just one of many circumstances in which the Y-STR DNA test can be applied. Review the chart above as a guide.

Testing: Two applicants with shared maternal lineage

X-SV Female Lineage Paternity TestThe X-SV female lineage DNA test is used to determine whether two or more females are related through their maternal lineage, or if male and/or female children have the same biological mother. The Mitochondrial DNA sequence variation is passed from females to their children and has a relatively infrequent mutation rate, thus it remains the same through many generations. (Males do not pass the X-SV they inherited from their mother to their children).

This DNA test focuses on the Mitochondrial DNA and results in a unique X-SV profile for each individual tested. It is important to note that this test will not differentiate women that are in the same maternal lineage or children with the same mother.

For example, if a female Child "A" and her alleged half brother Child "B" (Child "B" having a different father than Child "A") want to know if they have the same maternal biological grandmother, and they have the same X-SV profile, it is very likely that they are of the same maternal lineage. If the X-SV profiles do not match, then they neither share the same maternal biological grandmother, nor do they share the same maternal lineage.

This is just one of many circumstances in which the X-SV test can be applied. Review the chart to the right as a guide.

Testing: Two alleged twins

Establishes whether fraternal or identical twins, or siblings. Paternity and/or maternity can also be verified.

Testing: Child and both maternal or paternal grandparents

In cases where the mother or father is missing or deceased, this DNA test determines maternity or paternity by using the DNA from the Maternal or Paternal Grandparents.

Testing: Two females

An X chromosome test is used between female test participants who need to find out whether they have the same father. If the females involved have the same biological mother, they will need to include the mother's DNA sample in the test. If they have different mothers, they can carry out the test without the inclusion of the mother's sample.

In an X chromosome test we analyse a total of 10 genetic markers.

Testing: Child and alleged grandparent/aunt/uncle

This DNA test can be used to assess genes from the paternal (or maternal) side of the family, even when DNA from the alleged father (or mother) is unavailable, by establishing a link between the DNA of a child and the DNA of an alleged grandparent, aunt or uncle. It is important to note that grandparents, aunts and uncles will have only one quarter of their genes in common with a child, whereas parents and children have half their genes in common. Because of this two-fold dilution of genes, the test cannot achieve as accurate results as a parent-offspring DNA test. Nonetheless, it will provide a numerical probability for the alleged familial relationship.

Testing: Cousins

It is not possible to compare the DNA profiles of two individuals and reliably confirm if they are first cousins. Reputable DNA testing companies generally do not undertake first cousin analysis by testing just two people because the results are very likely to cloud the matter rather than clarify it. Please contact us for more information about alternative tests or visit our page on cousin DNA testing.

Testing: Child, mother and alleged father samples

Prior to a child's birth, Expedite can perform a prenatal DNA paternity test using DNA samples taken during the early stages of pregnancy (11-23 weeks). The unborn baby's DNA samples must be collected by an obstetrician or gynaecologist at a private clinic using either a CVS or an amniocentesis procedure. These procedures collect and cultivate cells containing DNA from the unborn child.

Testing: Expectant mother

We can offer a 4 to 6 working day rush service at an additional cost if you wish to shorten the turnaround time. Our baby gender prediction test is a unique DNA based test which uses only maternal urine samples to determine the gender of the baby with an accuracy of 99%.

Testing: Petitioning/ commissioning parent/s and child/children

We offer surrogacy DNA testing. This test can be used for a number of reasons. In many cases our clients seek a peace of mind test to verify that the correct embryo was implanted or that the sperm of the intended father was used during the IVF. We also offer surrogacy testing for immigration or legal cases where the commissioning parents need to prove their child is their biological offspring and thus, entitled to certain benefits including citizenship.

Testing: Applicant test only

Receive a hard copy of your unique DNA profile. DNA identification profiling has a number of uses and benefits including:

  • To assist in determining familial relationships.
  • To safeguard the rightful heirs and ensure that they will inherit your estate through the exclusion of false claims on your inheritance.
  • To avoid expensive exhumations if your DNA profile is required in the future.
  • As a precaution for any possible future identification/verification requirements for those who work in high risk jobs e.g. in cases of kidnapping, accidental death etc.
  • To ensure the availability of permanently stored records.
  • Testing: One item, e.g. underwear

    Is your partner cheating on you? Did you find a suspicious article of clothing such as stained underwear or other object? Expedite can provide you conclusive answers through DNA Infidelity Testing. DNA testing typically provides conclusive results that confirm or deny the presence of male and/or female DNA on suspicious items where the DNA source is unknown, unseen or potentially mixed. Once conclusive results are obtained, Expedite can also run powerful DNA comparative analyses to identify the source of the DNA. For an additional fee per sample we can also match the DNA profile obtained against DNA from mouth swab samples to establish who it belongs to.
