Pharmaceutical companies are seeking more than simply a
contract laboratory that can provide analytical results. Outsourcing has
evolved into a partnership between the client and the laboratory. The
author provides an overview of the current roles and responsibilities of a contract
laboratory and discusses the steps involved in building a successful
outsourcing partnership.
The relationship between contract laboratories and their
clients has evolved significantly over the years. In the 1970s, the
process of submitting a sample for analysis was fairly simple: A client would
call the laboratory, and a verbal agreement would be made. The laboratory would
receive the sample, complete the analysis, issue a final report, and mail the
report to the client. Today, however, both parties follow a completely different
process.
This article provides an overview of the current roles and
responsibilities of a contract laboratory and discusses some guidelines for
pharmaceutical companies to follow when evaluating the quality of a laboratory.
The goal in outsourcing is no longer simply submitting a sample for analysis and
obtaining a result. Today, prospective clients seek a contract laboratory with
whom they can develop an ethical, longstanding, proactive partnership.
Outsourcing involves a broad range of services. A pharmaceutical
company's needs can be long term, short term, and/or project specific. The main
benefit of hiring an outside laboratory is access to the in-depth technical
capabilities offered by a single organization. Outsourcing can eliminate the
need for additional staff, facilities, and/or equipment. Many clients prefer to
keep some projects in-house while outsourcing others that are more detailed and
sophisticated.
STEPS TO BUILDING A PARTNERSHIP
First, a company must select a contract laboratory. Because the
pharmaceutical industry is regulated by current good manufacturing practices (cGMPs)
and good laboratory practices (GLPs), the contract facility must be able to
perform analyses in accordance with these regulations. The client then must
determine its needs and expectations and communicate them to the laboratory.
Remember, the laboratory a client chooses should be considered an extension of
its own facility. The quality of the work performed on- and off-site must be
identical. It is the responsibility of both the pharmaceutical company and the
contract laboratory to ensure this quality.
If the contract laboratory defines guidelines that it advises
following (e.g., protocols and methodology), then the client has the obligation
to determine the validity and regulatory basis for these suggested guidelines.
Communication is key -after all, this is a partnership.
A company should create a comfort zone between itself and the
laboratory by visiting the facility and conducting an on-site evaluation. This
visit provides the client an opportunity to review standard operating
procedures (SOPs) and to get a feeling about the technical excellence of the
laboratory.
The client then must plan a facility audit. An audit is a tool to
evaluate a laboratory's processes. The audit should include a tour of the
facility and observation of the staff at work. The client should note how
comfortable it feels and/or is made to feel in the laboratory.
It is important that the laboratory have specific protocols in place
and, even more critical, that it follow these protocols. A company must evaluate
several key issues to ensure that the laboratory it selects is in compliance
with cGMPs and/or GLPs. General questions include
 | When was the laboratory's most recent FDA inspection? |
 | Were any 483s issued as
a result of the inspection? |
 | How did the laboratory respond to these 483s? |
SAMPLE MANAGEMENT ISSUES
Handling samples can seem like a juggling act. Specific protocols that
define the process must be in place to prevent anyone from dropping the ball.
The client should review
 | traceability (sample log-in, chain of custody, storage, etc.) .sample integrity
(What protocols ensure that integrity is never compromised?) |
 | sample deposition (What happens to the sample, and how is the process
documented?) |
CALIBRATION ASSESSMENT
The days of simply running an assay are long gone. Laboratories now are
required to prove their diligence and verify that their instruments, no matter
how simple or complex, operate within specified criteria. Key areas to evaluate
include
 | installation/performance qualification .operational/performance qualification |
 | general calibration (What is the time frame [how often]? What specification
criteria must be met?) |
 | instrument log books (Log books tell a story about the facility. How diligent
is the laboratory in following protocol?) |
 | maintenance (What program is in place to ensure that all equipment is
functioning properly? How is this documented?). |
REFERENCE STANDARDS
An assay depends on the quality (purity) of the standard against which it is
quantified. It is critical that criteria be defined for the handling of
standards within the facility. Some areas for the client to review include
 | storage |
 | labeling (it must be consistent) |
 | qualification of standards |
REAGENTS AND SOLUTIONS
In an analysis, a reagent is used by itself or as part of a solution
(typically a volumetric solution). A client should review all documentation for
 | consistent preparation |
 | standardization |
ANALYTICAL METHODOLOGY
Analytical methodology is a key area that must be evaluated in detail. Methods
must be suitable for analytical use. When CGMP regulations apply, all
methods of analysis must be validated. In particular, the client should ask
 | How are methods validated? |
 | What is the process for the transfer of analytical methodology? |
STAFF
Companies must ensure that the laboratory has documented evidence showing
that it verifies employee training. The company should
 | review the curriculum vitae |
 | review employee training records. The records must be detailed enough to
ensure that the staff members are qualified to perform the analyses to which
they are assigned |
 | ask if management participates in the training. |
DOCUMENTATION REVIEW
This step is the traceability path. A pharmaceutical company must be
confident that the integrity of the sample and all analyses will not be
compromised. The client should carefully review the laboratory notebook protocol
to ensure that a record will be in place that will allow the client to
reconstruct the analysis from the time the sample leaves its facility to the
time of archival of the final report.
Although it can be overwhelming, meticulous, detailed documentation
is critical for cGMP and GLP compliance. With documentation comes document
control. Clients should review the systems that are in place at the laboratory
to ensure full document control. Areas to evaluate include
 | SOPs (Review archives
of records and handling of raw data.) |
 | out-of-specification results (What is the
laboratory's protocol ? The laboratory must have a process in place to handle
these results.) |
CONCLUSION
Of course, the entire outsourcing process goes full circle. There are
critical steps from start to finish -from the time the sample arrives at a
client's facility to archival of the final report. If even one event is not in
compliance, the circle is broken. A proactive, successful outsourcing
partnership is created when both parties are committed to the process. All
analytical and regulatory needs must be met. A high level of integrity, trust,
and technical excellence must be established. In the end, both partners'
dedication to creating a beneficial alliance will drive long-term success.
