|DNA Paternity Testing|
1. Quality of testing
In theory, the fewer genetic loci involved in a paternity check, the lower ought to be the cost. However, while the standard these days is to check for at least 16 genetic loci, a less pricey check involving fewer loci would of lower quality, so you get what you pay for. Not only that, but the cost will even be influenced by the quality of 'consumables' used in the check: validated industry standards, such as promega kits, will be more pricey than those produced by the laboratory itself.
2. Time taken for the check
In general, the greater the number of subjects involved in the check, then the higher will be the cost. Sometimes, in dna paternity testing, no charge will be made for the check on the sister if that is included, but normally the cost will increase proportionate to the number of people involved.
3. Where the check is carried out
You will likely pay more in case you request a quick turn-round time. Fundamentally, the faster you require the results the more the check is likely to cost. In fact, the additional cost of having the results within 24-48 hours could be the same as the dna testing.
4. The type of check & nature of the sample
The cost of dna testing will vary according to the country in which the check is carried out. This variation is largely connected with the market demand for such testing, & in country such as the usa, for example, there is a much larger demand than is most other countries. The cost is then determined by competition & cost savings associated with high volume testing, & can be consequently lower than elsewhere.
Not all dna testing is carried out the same way, & some types of check will cost over others will. The cost you pay will depend largely on the type of check necessary, other variables being equal. Hence, the analysis involved in sibling tests are more complex than dna paternity tests, & the cost will be correspondingly higher. The situation is the same for other forms of dna relationship testing, & an additional factor that has implications on the cost is the type of sample submitted. Oral or buccal swabs are simpler to check than a hair sample, for example, & so the hair sample will cost more due to the additional preparatory work necessary.
5. Standard & legal testing
the additional cost of a legal dna check over a standard check is not generated by any difference in accuracy between the, because there is none. It is because of the additional costs involved in the legal check, & the additional responsibility that legal check implies. The kit used to collect the samples is usually more comprehensive & more pricey, the samples must be couriered to make sure no tampering through a proper chain of custody, an outside third party is necessary for notarization & appointments for sample collection must be set up. There's others, but each of these has a cost implication.
There are therefore several factors that influence the cost of a dna check, and that cost will be reflected in the cost charged. Due to the potential complexity of the pricing structure, then, you are advised to get the cost confirmed first before you order the check.
