I have a carefully (and expensively) worded disclaimer on my worm egg count reports. This was on advice of a lawyer who helped me combine the legal requirements with a clear statement that makes sure people understand the strengths and limitations of the test.
The alternative would be that I would have to carry such a high level of indemnity insurance that I would never do a single worm egg count for the general public.
Not all disclaimers are on a dodgy product. A disclaimer really should just be a simple statement showing that the person selling the product has clearly explained the limitations of the product or service they are providing and the person buying it understands what they can expect from the product
