FDA TO REGULATE RESEARCH ANTIBODIES

It is my understanding that the FDA does now require that reagents
that may be used for diagnostic uses (e.g., cancer markers, infectious
disease detection, etc.) are to be regulated.
However, it also appears the amount of regulation is minimal. They
require that the manufacturer follow good manufacturing practices.
These include proper labeling and documentation during the
manufacturing processes, as well as being able to field customer
complaints and document how you deal with these. The regs also require
that the company submit a notifcation with proposed labeling before
marketing the product. This is then reviewed by the FDA for truth and
For example, is the reagent is an antibody, then one must identify
what the antibody recognizes and be sure that all claims are accurate.
If this is only a reagent and not a kit, there can be no performance
claims. These reagents are intended for the user to establish the
assay method. The user (e.g., pathologist, laboratory) must "validate"
that the assay using this reagent performs well enough for diagnostic
uses. The end user must also assure continued performance.
If the manufacturer puts the reagent into kits or claims diagnostic
performance, then he needs to provide data to the FDA. Otherwise, he
mostly needs to just assure that the reagents are made well and
packaged without error.
For most smaller companies this may seem a burden at first, but
similar regs are being established in Europe under ISO regs.
Anyone else interpret this differently? To me, it doesn't look too
bad. I also doubt that true research reagents that are never or rarely
used in the clniical realm will ever be regulated. Remember, the FDA
can only come down on a company that sells these reagents to groups
that really do use them for human diagnostics.
