Dear Thierry:

I think I did send you a message yesterday thanking you for 
responding to my posting. Just in case I did not, I am doing it again.

You are right, we must find pleasure in complicating life. If we do not
watch out soon distilled water will be a Medical Device.

The problem is that they appear to expand they criteria of the
Medical Devices to an extreme that will surely result in serious 
damage to the scientific community in US.

To regulate as Medical Device a kit design for detecting PSA in 
blood is a reasonable regulatory activity of the FDA, however, 
to classify as Medical Devices all antibodies to PSA is unnecessary
and only reflects gross overregulation. There are thousands of
researchers using antibodies to PSA in many different ways. Why
should they be restricted of the use of these tools just because the
antibody has a clinical significance?

Because a heart pump implant is made of polycarbonate that should not
convert polycarbonate to be a Medical Device. The extreme of this 
regulation is such that a biotin-labelled goat anti mouse IgG and 
peroxidase labeled avidin are all considered Medical Devices. 
I honestly believe that if we continue on this course, distilled 
water will soon also be considered to be a Medical Device.

How ridiculous and silly are we going to allow this to get?

Someone told me the other day that the "tongue depressor" is 
a Medical Device. That explains the amount of money they charge 
in hospital bills for such a simple piece.You can be sure that 
the companies that make this prefer that the little stick be a 
Medical Device so that they can charge accordinly.

There is a posting on this newsgroup as well as in posted
by Biodesign which includes a lot of info on this antibody regulatory

I strongly recommend you to read their posting and learn what 
is cooking in the pot of FDA right next to your backyard.

Thank you again for your time and interest.

Best regards,
