The Importance of Computer Systems Validation

The Importance of Computer Systems Validation

Validation is essential in maintaining the quality of your products and a key requirement for GxP compliance. This is necessary not only for your facility, equipment, products, and processes but also for your computer systems. We focus here on computer systems validation. 

Computerized systems and software validation (CSV) provides evidence that your systems are compliant with current regulations and are suitable for their intended purpose. You want to proactively perform CSV to ensure that your systems do what you intend, maintain data integrity, and meet regulatory agency requirements. Your computer systems should protect against: damage, shutdowns, distorted research results, product and sample loss, unstable conditions, and any other bad outcome you can forecast.

Once you install and validate a computer system, you need to keep its hardware and software updated. You need to perform validation studies to show that these updates to hardware and software maintain the validated state of your computer system. These continuous validation measures enable you to avoid errors in computer systems that “magically appear” after software upgrades or hardware changes.

Also, you want to consider your computer system validation when you start a new product or upgrade an existing product. Ask the question, “Do we have evidence that the computer system will work for this new product or upgrade, etc.?” If your answer is No, consider validating your computer system for this change. Then you’re ready for a running start!



PSC Biotech can provide you the highest quality CSV services on any scale. Our Computer System Validation experts, experience, and processes prevent overlooking small details and help you smoothly implement robust validation procedures.

Effective Risk Management For Medical Devices

Effective Risk Management For Medical Devices

Risk Management is your system of management policies, procedures, analysis practices, and monitoring risk.  An effective risk management program is an essential element in the life cycle of a medical device.    

A Hazard is a potential source of harm.  A Risk is your estimated probability that a Hazard occurs for your medical device and the severity of that Hazard to patients, users, etc.  So, how do you do risk management?  You start with ISO 14971.

ISO 14971 is the International Standard that specifies terminology, principles and a process for risk management of medical devices, software as a medical device, and in-vitro diagnostic medical devices. 

The ISO 14971 process will help you identify the risks associated with your medical device, to estimate and evaluate the risks, the measures you use to control these risks, and to monitor the effectiveness of your controls.  Your risk management process applies to the full spectrum of risks including, but not limited to  biocompatibility, data and systems security, electricity, moving parts, radiation, maintenance, calibration, transport, and usability.  ISO 14971 does not specify acceptable risk levels.  You set objective criteria for risk acceptability and you set the acceptable risk levels.

medical device

Remember, an effective risk management program isn’t just a one-time exercise, it is an ongoing part of your product life cycle. Effective risk management helps you protect your patients, your products, and your reputation.

ISO has recently updated ISO 14791 with ISO/TR 24971:2020.  This technical report includes additional guidance on the principles and the process for managing risks associated with software as a medical device (SaMD) and in-vitro diagnostic (IVD) medical products.  You want to review and update your risk management process to apply the principles in ISO 14971 and technical report ISO/TR 24971 to make your risk management program optimally effective.

PSC Biotech® has experienced risk management professionals who can help you establish your program and provide risk management services tailored to your needs.  Call us today and let’s talk about effective risk management.

How Outsourcing Professional Services Can Boost Your Company

How Outsourcing Professional Services Can Boost Your Company

Written by: Tom Kelland, Director of Southwest Operations at PSC Biotech™

Utilizing outsourced professional services can help boost your company in many different ways. This is especially true when working in a heavily regulated industry where expertise will save time and minimize costs. Outsourcing professional services provides benefits to companies of all sizes, including:

  • Gives your employees more time – Outsourcing specific professional services gives your employees more time to perform their routine activities. By not having to learn new functions that are outside the scope of their core role your employees can focus on their essential tasks.
  • Quality Assurance – Using experts provides assurance in the quality of work that is performed. This means no rework or editing work, when it is complete you can move onto other tasks.
  • Less Human Resources Requirements – Employee management can be costly and complicated! By outsourcing professional services there is no need to worry about employee management and the costs associated.
  • Availability of Expertise – Sometimes there are problems that your company will face that no one within your organization has the expertise to resolve. By outsourcing your professional services, you have expert resources at your fingertips.
  • Work Gets Done Quicker – Outsourcing leaves complicated tasks to experts who have experience executing similar work. This results in tasks getting done sooner than they would have if you kept the task for your own employees. This helps you meet tight timeframes.
  • Accelerate the Learning Curve of Your Employees – Your own employees don’t have to slowly learn the task at hand and absorb the mistakes that come with that learning. Expert professional service providers can train your employees while executing tasks to accelerate the learning curve of your employees without the risk of costly mistakes that slow your operation.
  • Have Better Control of Your Varying Workload – Your workload can vary greatly depending on initiatives and demands in the market. When you outsource professional services you don’t have to take on the risk of hiring full time employees for the times when workload is high. Outsourcing allows your business to adapt easily when a workload surge decreases so you can maintain a lower headcount.

It is clear that outsourcing professional services will help your company with time and cost savings, flexibility, subject matter expertise, and quality of work. Outsourcing lets your team focus on their core work, spend less time and avoids costly mistakes.

Starting A New Laboratory

Starting A New Laboratory

Written By: Matthew Greer, Technical Writer, PSC Biotech®


Starting up a new laboratory can be a daunting task. What regulations need to be followed?  What kinds of products are you handling?  What kinds of tests will you do?

Once you know this, you need to consider the best layout for your laboratory.  You need to identify the test and laboratory safety environment.

Let’s discuss a few of the factors you want to consider in planning your new laboratory.  First, having the right team is essential, and if you need help, PSC Biotech® has the resources that you need.

Avoid the Common Mistakes

Before breaking ground, you need to consider how will you laboratory be utilized? What products will be tested in this lab? What are the methods associated with these products?

Are there any safety equipment or special requirements necessary for each one? Fire extinguishers, eye wash stations?  Fume hood, Biosafety Hoods, Glove boxes? Gowning, Degowning?  Chemical and Biohazard Waste storage?  Autoclave or Dry Heat Oven?  Flammable, Acid, Base, and Oxidizer storage?  Personnel low, Sample flow, Sample Storage?  Design your laboratory on paper first.

You must understand the tests the laboratory will be asked to perform, including chemistry and microbiology tests for raw materials and in-process, final product, stability, and validation samples. 

Next you need to select the appropriate test equipment to perform the tests.  How accurate, how precise, how sensitive, etc. does the equipment have to be?  Oh yes, and remember that everything needs to calibrated.

Which type of utilities will be needed? Electricity, Gas, Air, Nitrogen, Vacuum, Water?

Do you need Purified Water, Water for Injection, Distilled Water? Make sure the correct water systems are installed for your planned testing.

Do you need to control the laboratory temperature and relative humidity?  How about vibration or light?  Do you need an ISO classified environment, such as an ISO 5 room or hood for aseptic operations?

Don’t forget the Paperwork

What about your quality management system?  Policies, procedures, forms, records, etc., are essential.  If it isn’t documented, it didn’t happen. If you need a Quality management System that is plug and go, consider ACE Essentials™, our cloud-based fully cGMP compliant system that comes with all the necessary Standard Operating Procedures (SOPs), quality event management, training management, and even more features to have your new laboratory in compliance from its very start.

What is Method Transfer, and Why is it Important?

What is Method Transfer, and Why is it Important?

Written By: Mattew Greer, Technical Writer, PSC Biotech®

When bringing new products from one facility to another or from a product development to production environment , understanding the requirements for the transfer of validated analytical methods used for testing of said products is essential. It is important to compare the initial and transfer laboratories and confirm that the latter has the capability to perform the validated method correctly and consistently. The transfer needs to check that the methods adhere to the United States Pharmacopeia (USP) and any other applicable standards as well. The goal in a successful method transfer should be to reduce the number of variables in your lab which could affect the quality of the final product. These methods need to be taken from the primary lab and transcribed into approved documents for testing at the final lab. This paper will list some of the various types of method transfer possible and how PSC Biotech® can provide assistance.

Method Transfer Types

There are typically four different types of method transfers that are based on the availability of the initial testing lab as well as the complexity of the products being tested.

Comparative Testing

Comparative Testing means to test a predetermined number of samples of the same lot by both the sending and receiving facilities and comparing the results. The transfer protocol from the initial lab will determine the acceptance criteria and procedures.



If both the initial and transfer site needs to collaborate to complete the validation, the appropriate transfer method is to co-validate. This would mean keeping lines of communication between both sites in order to confirm the reproducibility. This strategy is optimal for dealing with multiple laboratories. Similar to the comparative testing, the protocols will come from the primary site.


This type of testing is necessary if the initial laboratory is not available to receive the proper methods. Revalidation is the most consuming of all the method transfers but needed when the initial lab is not accessible. Usually this work involves repeating all validation testing initially performed.

Transfer Waiver

Depending on the lab’s experience and the complexity of a method, opting for a transfer waiver is a viable option for some transfers. A risk assessment would need to be taken into consideration to confirm this approach is valid.

What Can PSC do for you?

Method transfer can easily become a hassle, and that is where PSC Biotech® can help. We employ a team of professional consultants who are available to transition documents with ease. Our services are offered in the form of a local team who can come onsite to collaborate to make sure your facility is ready for any type of method transfer.
