Sec. 809.10  Labeling for in vitro diagnostic products.


    (a) The label for an in vitro diagnostic product shall state the 
following information, except where such information is not applicable, 
or as otherwise specified in a standard for a particular product class 
or as provided in paragraph (e) of this section. Section 201(k) of the 
act provides that ``a requirement made by or under authority of this act 
that any word, statement, or other information appear on the label shall 
not be considered to be complied with unless such word, statement, or 
other information also appears on the outside container or wrapper, if 
any there be, of the retail package of such article, or is easily 
legible through the outside container or wrapper.''
    (1) The proprietary name and established name (common or usual 
name), if any.
    (2) The intended use or uses of the product.
    (3) For a reagent, a declaration of the established name (common or 
usual name), if any, and quantity, proportion or concentration of each 
reactive ingredient; and for a reagent derived from biological material, 
the source and a measure of its activity. The quantity, proportion, 
concentration, or activity shall be stated in the system generally used 
and recognized by the intended user, e.g., metric, international units, 
etc.
    (4) A statement of warnings or precautions for users as established 
in the regulations contained in 16 CFR part 1500 and any other warnings 
appropriate to the hazard presented by the product; and a statement 
``For In Vitro Diagnostic Use'' and any other limiting statements 
appropriate to the intended use of the product.
    (5) For a reagent, appropriate storage instructions adequate to 
protect the stability of the product. When applicable, these 
instructions shall include such information as conditions of 
temperature, light, humidity, and other pertinent factors. For products 
requiring manipulation, such as reconstitution and/or mixing before use, 
appropriate storage instructions shall be provided for the reconstituted 
or mixed product which is to be stored in the original container. The 
basis for such instructions shall be determined by reliable, meaningful, 
and specific test methods such as those described in Sec. 211.166 of 
this chapter.

[[Page 85]]

    (6) For a reagent, a means by which the user may be assured that the 
product meets appropriate standards of identity, strength, quality and 
purity at the time of use. This shall be provided, both for the product 
as provided and for any resultant reconstituted or mixed product, by 
including on the label one or more of the following:
    (i) An expiration date based upon the stated storage instructions.
    (ii) A statement of an observable indication of an alteration of the 
product, e.g., turbidity, color change, precipitate, beyond its 
appropriate standards.
    (iii) Instructions for a simple method by which the user can 
reasonably determine that the product meets its appropriate standards.
    (7) For a reagent, a declaration of the net quantity of contents, 
expressed in terms of weight or volume, numerical count, or any 
combination of these or other terms which accurately reflect the 
contents of the package. The use of metric designations is encouraged, 
wherever appropriate. If more than a single determination may be 
performed using the product, any statement of the number of tests shall 
be consistent with instructions for use and amount of material provided.
    (8) Name and place of business of manufacturer, packer, or 
distributor.
    (9) A lot or control number, identified as such, from which it is 
possible to determine the complete manufacturing history of the product.
    (i) If it is a multiple unit product, the lot or control number 
shall permit tracing the identity of the individual units.
    (ii) For an instrument, the lot or control number shall permit 
tracing the identity of all functional subassemblies.
    (iii) For multiple unit products which require the use of included 
units together as a system, all units should bear the same lot or 
control number, if appropriate, or other suitable uniform identification 
should be used.
    (10) Except that for items in paragraphs (a) (1) through (9) of this 
section: (i) In the case of immediate containers too small or otherwise 
unable to accommodate a label with sufficient space to bear all such 
information and which are packaged within an outer container from which 
they are removed for use, the information required by paragraphs (a) 
(2), (3), (4), (5), (6) (ii), (iii) and (7) of this section may appear 
in the outer container labeling only.
    (ii) In any case in which the presence of this information on the 
immediate container will interfere with the test, the information may 
appear on the outside container or wrapper rather than on the immediate 
container label.
    (b) Labeling accompanying each product, e.g., a package insert, 
shall state in one place the following information in the format and 
order specified below, except where such information is not applicable, 
or as specified in a standard for a particular product class. The 
labeling for a multiple-purpose instrument used for diagnostic purposes, 
and not committed to specific diagnostic procedures or systems, may bear 
only the information indicated in paragraphs (b) (1), (2), (6), (14), 
and (15) of this section. The labeling for a reagent intended for use as 
a replacement in a diagnostic system may be limited to that information 
necessary to identify the reagent adequately and to describe its proper 
use in the system.
    (1) The proprietary name and established name, i.e., common or usual 
name, if any.
    (2) The intended use or uses of the product and the type of 
procedure, e.g., qualitative or quantitative.
    (3) Summary and explanation of the test. Include a short history of 
the methodology, with pertinent references and a balanced statement of 
the special merits and limitations of this method or product. If the 
product labeling refers to any other procedure, appropriate literature 
citations shall be included and the labeling shall explain the nature of 
any differences from the original and their effect on the results.
    (4) The chemical, physical, physiological, or biological principles 
of the procedure. Explain concisely, with chemical reactions and 
techniques involved, if applicable.
    (5) Reagents:
    (i) A declaration of the established name (common or usual name), if 
any, and quantity, proportion or concentration or each reactive 
ingredient; and

[[Page 86]]

for biological material, the source and a measure of its activity. The 
quantity, proportion, concentration or activity shall be stated in the 
system generally used and recognized by the intended user, e.g., metric, 
international units, etc. A statement indicating the presence of and 
characterizing any catalytic or nonreactive ingredients, e.g., buffers, 
preservatives, stabilizers.
    (ii) A statement of warnings or precautions for users as established 
in the regulations contained in 16 CFR part 1500 and any other warnings 
appropriate to the hazard presented by the product; and a statement

etc.
    (iv) Appropriate storage instructions adequate to protect the 
stability of the product. When applicable, these instructions shall 
include such information as conditions of temperature, light, humidity, 
and other pertinent factors. For products requiring manipulation, such 
as reconstitution and/or mixing before use, appropriate storage 
instructions shall be provided for the reconstituted or mixed product.
