DO NOT disturbed the sample, only handle the item to place it in the envelope or paper bag to ensure the sample is intact. Handle the item(s) with gloves or a clean dry paper towel.
DO NOT put more than one sample to be tested in the envelope or paper bag. If you are sending more than one piece of clothing, or a towel, or sheet, etc. for a semen detection test, place each one in a separate bag and label.
If you are sending swabs for the semen detection test, you may place those in an envelope together.
DO wear gloves when handling the sample and mark the area for testing with a Sharpie marker. Draw a circle around the area that contains the suspected semen stain. The lab will require to know the exact area to be tested.
If the item is large (e.g. sheet, large piece of clothing) cut around the area containing the semen stain, leaving as much room around it. Remember to wear gloves.
DO NOT send samples for testing that are obviously wet. Allow thorough air drying prior to packaging.
DO NOT place the sample in any sort of plastic bag. ALWAYS use a clean dry envelope or paper bag. This will protect the DNA on the sample in the event further DNA testing is required further than just semen detection testing.
