Question :. How does the FDA interpret the regulations 21 CFR Part regarding the establishment of expiry dating for chemicals, reagents, solutions, and solvents? Answer :. Laboratory reagents and solutions are used in analytical tests of components, in-process materials, and finished products. For purchased laboratory reagents and solutions without a “use by” or expiry date, FDA would expect that an assessment be conducted literature review may be acceptable of that specific chemical’s or chemical family’s stability and that an appropriate “use by” or expiry date be determined.
For in-house prepared solutions, such as mobile phases or other non-quantitative solutions, FDA would expect that an assessment be conducted again, literature review may be acceptable to determine an appropriate expiry period. However, for in-house prepared solutions used for quantitative analysis, such as sample or standard solutions used in assay or impurity testing or titration solutions, FDA requires that formal stability studies be conducted to determine an appropriate expiry.
As mentioned in Guidance for Industry: Q2B Validation of Analytical Procedures: Methodology, the stability of analytical solutions is a typical method variation that should be evaluated during robustness testing during method validation. Method validation is a CGMP requirement at The determined “use by” or expiry dates should be documented within a procedure and followed.
Expiry Dating for Reagents and Solutions in Laboratories: What are FDA’s Expectations?
Recently, my colleagues and I faced a huge dilemma during our lab clean-up. Should we toss it away? Or can we still keep it for use? According to the Certificate of Analysis, reagent B does not have an expiration date, does it mean that it can be used indefinitely? Hoping to find answers to our problems, I went online and was disappointed to find no straightforward solutions from the manufacturers.

Handling and Storage of Urine Reagent Strips. The following precautions should be observed when handling and storing urine reagent strips: Store strips according to the manufacturer’s recommendations. DO NOT expose strips to moisture, volatile fumes, or direct sunlight. Remove only enough strips for immediate use and immediately recap the bottle.
Avoid contamination of test strips. Do not touch the test areas with fingers and do not lay test strips directly on the workbench. DO NOT use discolored strips. Compare the color of the unused strip to the negative area on the color chart provided by the company. The color should be similar. Check the expiration date. Re-label the container with a revised expiration date if the manufacturer states a shortened usage period once the container has been opened.
Procedural Precautions Although the procedure is simple to perform, accurate results depend on careful adherence to manufacturer’s directions and adequate quality control. Normal and abnormal controls should be tested whenever a new lot of strips is opened, and at the frequency defined by the laboratory’s procedure. If quality control results do not correspond to the published control values, the problem must be resolved before patient samples are tested.
How to Keep Your Lab Stockroom and Cold Reagents Organized

Designate specific, clearly-labeled storage locations for each reagent or category of reagents to ensure that newly-delivered items can easily be found by all lab members. Have a discussion with your lab mates to determine which commonly used reagents should be kept within arm’s reach on the lab bench and which rarely used reagents can be stored away. You can also reduce clutter by creating a schedule for going through your reagents and removing expired and obsolete reagents from your storage space.
Establish a consistent labeling system that all lab members use to label aliquots and shared solutions.

Method validation is a CGMP requirement at. The laboratory “use by” or expiry dates should be expiry within a procedure and followed. Procedures for any in-house prepared laboratory solution should include the determined stability expiration, date should instruct that these solutions be labeled with laboratory appropriately determined “use by” or expiration date upon preparation and discarded upon expiration. These principles would also apply to FOR manufacturing and testing sites. Expiry Dating for Reagents and Solu.
