This is not a scam because it's not about money. If you have ins. they will file for you, if no ins. they will test you anyway. They send you a kit to send them a sample using a long swab and a vial of liquid that you return to them. It takes about 3 weeks for results. they will give you extensive report with species found, your level of probiotics present and they sell no products, just give advice to improve your gut health depending on what species are present.
