Expiry Dating for Reagents and Solutions in Laboratories: What are FDA’s Expectations?

Establishment of expiry dating for chemicals, reagents, solutions, and solvents? 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. 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. Procedures for any in-house prepared laboratory solution should include the determined stability timeframe, and should instruct that these solutions be labeled with the appropriately determined “use by” or expiration date upon preparation and discarded upon expiration. These principles would also apply to API manufacturing and testing sites. More detail click or tap here. Post a comment.

NCBI Bookshelf. This chapter organizes the discussion of managing laboratory chemicals into six main topics: reducing and eliminating the use and generation of hazardous substances green chemistry ; acquisition; inventory and tracking; storage in stockrooms and laboratories; recycling of chemicals and laboratory materials; and transfer, transport, and shipment of chemicals.

As Chapter 1 makes clear, prudence in these areas requires knowledge of the hazards posed by laboratory chemicals and the formulation of reasonable measures to control and minimize the risks associated with their handling and disposal. Not all risk can be eliminated, but through informed risk assessment and careful risk management, laboratory safety is greatly enhanced. Trained laboratory personnel, laboratory supervisors, and individuals who handle chemicals will find essential information in this chapter.

Each person has an important role to play in a chemical’s life cycle at an institution, and each one of them should be aware that the wise management of that life cycle not only minimizes risks to humans and to the environment but also decreases costs. Acknowledging this role and giving it due consideration is one element of the culture of safety within a laboratory. Green chemistry is the philosophy of designing products and processes that reduce or eliminate the use and generation of hazardous substances, which fits well with the overall goals of a culture of safety.

The 12 principles of green chemistry Anastas and Warner, can be applied in the laboratory as guidelines for prudent experimental design and execution. Some of the principles are explained in more detail below, with examples of their broader application.

Determination of the expiration date of chemical solutions

We have all been guilty of using reagents past their expiration date. Usually we can get away with it, but there are a few things to beware of. Manufacturers guarantee their reagents but only if you have stored and handled them according to their recommendations. Caution: If your buffers have precipitated, this is usually an indication that you have done something wrong. Have you made up your stock with the wrong buffer?

Expiry date vs. Best Before Date – Reagents

But to maintain the original high degree of purity certain procedures should be observed with regard to storage and handling. For example, impurities can form due to thermal or photolytic decomposition as well as through formation of free radicals. Adverse reactions with atmospheric oxygen can produce dangerous peroxides and dryness can be degraded by contamination with atmospheric moisture. Effects of this kind differ from product to product and can be more noticeable over a period of time, especially when combining the sensitivity of modern analytical instrumentation with the very high purity of ROMIL laboratory products.

Applicability This document applies to all personnel of AHS Laboratory Services, the Should a product be required to be used beyond the expiration date, Background Chemical, reagent or solution degradation may be attributed to, but not.

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. Instead, I had a surprise finding—there is a huge online community who is as confused as I am.

A simple search on Research Gate revealed a countless number of questions relating to the use of expired reagents and advice to better manage inventories.

they can be consumed before the reagent expiration date. Volumetric Flask required for analytical laboratory use and processing solution preparation is given.

Quality control samples are special specimens inserted into the testing process and treated as if they were patient samples by being exposed to the same operating conditions. The purpose of including quality control samples in analytical runs is to evaluate the reliability of a method by assaying a stable material that resembles patient samples.

Quality control is a measure of precision or how well the measurement system reproduces the same result over time and under varying operating conditions. Pathologists need to be involved in development of quality control protocols, the selection of quality control materials, long term review of quality control data, and decisions about repeating patient samples after large runs are rejected. These quality control activities play an important part in assuring the quality of laboratory tests.

Quality control material is usually run at the beginning of each shift, after an instrument is serviced, when reagent lots are changed, after calibration, and when patient results seem inappropriate.

All working solutions and stains are properly labeled and dated. Chemicals and reagents are not to be used after the expiration date and are MSDS labeled.

Need Help? Barcodes store information. Usually, that information is related to the identification of a product, but sometimes it can include additional information. The catch here is that barcodes can only store a very limited amount of information and since that information is printed directly on the label it remains static. This is where RFID comes in handy, with much larger data storage capacities than barcodes, RFID can store a lot more information—and that information can be updated.

By including a writing module on the analyzer device itself, you can write an incrementing variable to the tag and use the variable in the user interface UI to display the amount of useful life or the number of tests remaining. For example, if one reagent pack allows for tests, that variable can be written into the tag. From there, each time the tagged pack is scanned by the analyzer device the number of remaining uses will drop by one.

Once the remaining uses on the pack reaches zero the user will be notified by the UI on the analyzer device that the pack is no longer useable. But what if a pack expires before it reaches the maximum allowed amount of tests? If in addition to the number of uses, you encode and track expiration dates, you can also set up your system to notify users when a pack is no longer suitable for use. Additionally, you can add a color coding system to the interface that allows users to view remaining life visually.

How to Handle Lab Reagents After Their Expiration Date

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.
