Do individual paternity test can be collected samples for the parties who do not want to identify the agency for sampling, but only want to provide their own identification samples, according to the difficulty of sample identification, the collection of conventional samples and special samples to be sent. Among them, routine samples of blood traces, hair with hair follicles, oral swabs; special samples of saliva, toothbrushes, chewing gum, mouth cups, nosebleeds, betel nut residue, semen spots (fluid), nails, etc..
The parties can choose to sample according to their own convenient collection of samples, but it should be noted that special samples may have incomplete sample DNA information, and the risk of sending additional samples, in addition, the processing of special samples are more complex, and their identification costs are relatively higher than the cost of conventional samples.
The director of the paternity agency recommends that the parties privately commissioned paternity test, want to provide their own identification samples, it is best to choose to collect a conventional sample, and in the conventional sample, it is recommended that the preferred oral swab sample. This is because the oral swab sample collection non-invasive pass, and suitable for all age groups, very convenient and simple, and preservation time is relatively long.
Oral swab sample collection method.
1, first prepare a medical swab, paper evidence package bag, and wear disposable gloves, mask. Then fill out the evidence bag and mark the date of sample collection. Draw two to three sheets of clean toilet paper on the desktop.
2, before sampling, give the appraisee a glass of water, ask him to simply rinse his mouth to remove the residual food residue in the mouth (such as the appraisee is an infant, ask his guardian to feed a small amount of warm water first), and then ask the appraisee to open his mouth naturally, with a medical swab on his tongue or buccal mucosa (both sides of the cheeks in the mouth) and turn the swab 3-5 turns. In the same way, take 2-3 swabs of samples and put them on a clean paper towel to dry.
3, the sample is verified, the swab just taken into the sample of the paper evidence package bag filled with information corresponding to the identified person. And send it to the testing facility as soon as possible.
Saliva DNA sample collection tube Collection method
1, Gently spit the saliva secreted in the mouth into the oval collection port of the saliva collector, taking care to avoid excessive foam when collecting the saliva.
2, Collect the saliva until the stratified interface between the saliva in the collection tube and the upper layer of foam reaches the scale line shown in 2 ml.
3, Snap the lid of the collector with the preserved liquid evenly onto the oval collection port. A slight clicking sound when snapping it off and a uniform flow of preserved liquid into the collection tube at the same time indicates that the lid has been snapped off, otherwise, the lid of the collector needs to be opened gently and then snapped on evenly again until the preserved liquid flows into the collection tube evenly.
4, Gently shake the saliva collector to make the preserved liquid flow into the collection tube more completely.
5, Confirm that the stratification interface between the liquid in the collection tube and the upper layer of foam reaches the scale shown in 4 ml.
6, Confirm that the collection is completed without errors.
