Special Stains: addressing questions through increased efficiency

Specific staining provides information to better inform treatment decisions
While routine H&E staining remains the cornerstone of histological tissue examination, Special Stains can play an integral role in a patient’s journey.
 

Special Stains provide pathologists with an increased level of detail, enabling the easy visualization and identification of specific cells, tissue types, cellular products, and morphology of microorganisms needed for a precise diagnosis.1,2

While this information empowers pathologists to better inform treatment decisions, manual processes and inefficiencies in the laboratory workflow have the potential to reduce productivity, which may in turn affect decision-making regarding the use of specialized testing.

 

Challenges of manual methods for Special Stains

Quality and consistency:

 

Special Stains are sensitive and subject to high variability depending on the stability of reagents as well as the skill level and experience of the technician

Technician safety:

 

As many Special Stains reagents include toxic components, their preparation, storage and disposal are potentially hazardous for laboratory personnel

Automated special stains sample processing
Workflow efficiency:
 

Manual preparation and application of reagents to tissue samples is time-consuming and laborious

Patient Safety - Elderly man with girl
Manual tracking:
 

Manual tracking of patient samples is tedious and cumbersome, and can lead to errors in accurately associating the result to the right patient

Add value efficiently - automate Special Stains
In the business of care, pressure to minimize cost is unavoidable. However, the drive toward efficiency can serve as a catalyst for change, benefitting patients and pathologists alike. 
 

In the laboratory, automation has well-established utility for routine testing, helping to reduce errors, optimize technicians’ time, and achieve more with less. As health systems continue to shift from a volume-based to value-based business model of care, streamlining workflows for specialized testing can help elevate the value provided by the laboratory.

The journey to more personalized patient care is rife with uncertainty, and Special Stains play a key role in bringing confidence to clinical diagnoses.

Patients, pathologists, technicians, and healthcare systems can all benefit from the automation of routine and specialized testing. Roche’s automated Specials Stains solution helps laboratories increase cost-effectiveness, day-to-day staining consistency, and safety for patients and personnel.

Now, laboratory staff can deliver patient results across a broader spectrum of stains more confidently and efficiently.
