Collecting a sample is easy
Our home PFAS test uses a special microsampler to make collecting your blood sample as easy as possible
It comes with the sampler in a foil package; 1 Gauze pad; 2 bandages; 1 alcohol prep wipe; 1 sample label; 3 sterile lancets; a prepaid mailing label; and a mailing envelope
Open the sampler, uncap the lancet, and open the wipes, gauze and adhesive bandages. Lay these out carefully on a table so they are ready to use.
Wash your hands with soap and warm water and dry them. Rub your hands together to make sure they are warm. If you have poor circulation, try shaking your hands at waist level for a minute or do some gentle exercise.

Clean the tip of the middle or ring finger on your non-dominant hand using an alcohol wipe. Use the lancet to make a prick to one side of the center of your finger tip.
Let the first drop of blood form and wipe it away with the gauze. The gauze should be disposed of.

Hold the sampler as shown in the video and touch the first tip to the drop of blood. Hold it until the tip is completely filled with blood, wait for 2s, then move the tip away. Repeat for all 4 tips.

When you have collected your sample, click the cartridge container closed. Write the following details on the label: First and last name; Contact phone number; Date of birth; Time you finished collecting the sample. Stick your completed label over the Neoteryx label on the cartridge (don't cover the ID label on the back)
Put the sample cartridge back in the silver sample bag, making sure the desiccant card is still inside.
Finally, put the sealed sample bag in the return envelope, close the envelope and put the return label on the outside. You can return it at any USPS post office or post box. Please mail the sample on the same day you collect it.
It’s important you collect at least 2 good samples. The lab will reject samples that are not good.
There are 2 common reasons to not collect a full sample: Removing the tip from the blood drop before it has completely turned red; or insufficient blood flow (see below).
A bad sample happens when there’s too much blood on the sampler tip. This happens when you put the tip of the device too deep into the blood, if you try to drip the blood onto the tip, or when you hold the tip facing upwards and hold the tip to the blood drop
You may have insufficient blood flow. If this happens, try massaging from the base of the finger up to the tip and touch the collector to the blood again. If there is still not enough blood, you can try pricking another finger.
