The packs contain specimen pots, gloves, pre-paid envelopes, easy to understand instructions and vouchers for a full laboratory test. It is extremely important that the samples are fresh and reach the laboratory the following day. This can be achieved provided the samples are posted by the last post on the day they are collected during the working week. The results and an explanation will be posted to the customer and there are no hidden charges once they have bought the pack. Horses must not have been wormed 10 - 14 days prior to testing.
