RAL Diagnostics : Quelles floorutions of staining and of preparationof samples for diagnosticss ?

A specialist in staining and sample preparation, RAL Diagnostics supports day-to-day haematology, cytology, microbiology and histopathology laboratories. Its portfolio spans ready-to-use reagents, rapid kits and accessories designed for reproducible, clear and standardised results. Part of the CellaVision Group, the brand enhances digital morphology workflows with a tightly controlled pre-analytical phase. From hospital core labs to QC and R&D laboratories, it safeguards slide quality and diagnostic confidence.

French laboratory expertise with a global reach

Born at the bench, RAL Diagnostics has made its mark with a simple idea: ready-to-use stains and reagents that are stable and reproducible, saving time without compromising quality. Over the years, the brand has expanded its expertise from haematology (Romanowsky, May-Grünwald-Giemsa, rapid staining kits) to cytology (Papanicolaou), microbiology (Gram, Ziehl-Neelsen, auramine) and histopathology (H&E, mounting media). Integration into the CellaVision group strengthens this trajectory by aligning slide preparation with digital morphology. The RAL culture remains intact: robust protocols, practical ergonomics, and a commitment to standardisation that streamlines training, high-throughput routine work and quality assurance in modern laboratories.

Expertise and areas of specialisation

Designed for everyday routines as well as demanding technical platforms, RAL Diagnostics solutions stand out for their colour consistency and straightforward implementation. In haematology, rapid kits such as RAL 555 and May-Grünwald-Giemsa stains deliver crisp contrast on blood films, faithfully preserving the morphological detail of RBCs and WBCs. In cytology, the Papanicolaou sets and fixatives ensure sharp nuclei, clean cytoplasms and even slides, even at high throughput. On the microbiology side, Gram and Ziehl-Neelsen reagents offer controlled timing and reproducible results, compatible with manual protocols or automated stainers. For histopathology, H&E, dehydration and mounting solutions promote colour stability and slide preservation. RAL focuses on ease of use (ready-to-use, colour coding, practical bottle sizes), traceability (lot information, technical data sheets) and operator safety (validated protocols, comprehensive documentation). Backed by CellaVision, the brand integrates naturally into digital morphology workflows: standardised preparation upstream for reliable downstream acquisition and interpretation. Result: clean slides, controlled process times and consistent quality, day after day.

Frequently asked questions about RAL Diagnostics

Are RAL stains compatible with manual use and automated stainers?
Yes, many ranges are designed for both workflows. Check each product’s labelling and instructions for use to select the appropriate protocol.

Does RAL offer rapid kits for haematology?
Yes. Rapid kits such as RAL 555 deliver short staining times and consistent, reproducible contrast, ideal for high-throughput routines.

Are the reagents compliant with in vitro diagnostic requirements?
Depending on the reference and intended use, many RAL solutions are intended for in vitro diagnostics in Europe. Refer to the labelling and the instructions for use.

How does RAL integrate with CellaVision solutions?
By standardising slide preparation, RAL strengthens the pre-analytical step and optimises digital morphology for review and interpretation.

What about traceability and documentation?
Each reference comes with technical datasheets and batch data. SDS and storage recommendations support quality and compliance.
