On rare occasions we are unable to obtain any DNA profile, a complete DNA profile, or there may be issues with contamination/mixed profiles. The actions we will take are as follows:
1) Discoloured (e.g. due to food/nicotine) swabs or mouldy swabs (due to the long time taken to return them to us) will not be used. We will inform you of this point via e-mail and offer you a replacement kit for a charge of £12.50.
2) If we have started the laboratory work and find an issue such as no DNA on the swab, mixed profiles or adulteration, then we will inform you of this point and offer re-sampling for a charge of £44. If we do not gain enough DNA from one swab to complete the test, we will conduct the work once more, then process the second swab before taking the decision to re-sample. This can cause a delay to your expected completion date.
