It's not a testing kit to do yourself. You have to mail it to get results. If that's the case I would of just gone to the local lab that every town has. Wouldn't of had to wait for delivery and now the delivery of the results as well. My fault though for not going into the description and checking. Their fault for not putting it In the title, you give the perception of doing this yourself at home. Extremely disappointed.
Test kit came w everything you need including bag and postage paid and labeled envelope. Includes very simple step by step instructions w pictures. Definitely would buy again!
