Pathology laboratories play a critical role in diagnosing disease through the examination of tissues, cells, and bodily fluids. Behind the scenes, efficient and accurate pathology work relies not only on skilled technicians and advanced instruments, but also on a wide range of consumable supplies that ensure sample integrity, workflow efficiency, and consistent results.
In this article, we explore the top 10 must-have consumables that every pathology lab should stock to operate safely, effectively, and in compliance with quality standards.
1. Paraffin Wax
Paraffin wax is essential for tissue embedding and block preparation. It provides the support needed to section tissues thinly and uniformly for microscopic analysis. High-quality paraffin ensures clean sections, minimal artifacts, and excellent preservation of tissue morphology.
2. Tissue Cassettes
Used during tissue processing and embedding, cassettes securely hold samples and allow for easy identification. They must be resistant to processing chemicals and designed to ensure proper reagent flow. Color-coded or pre-labeled cassettes improve traceability and lab efficiency.
3. Embedding Molds
These reusable metal or disposable plastic molds are used to shape the paraffin blocks for microtomy. The choice of mold size and type affects how well tissue samples are preserved and sectioned.
4. Microtome Blades
Microtome blades are vital for producing ultra-thin sections of embedded tissue. High-quality disposable or reusable blades ensure precision cuts, reduce tearing or compression artifacts, and prolong equipment lifespan.
5. Glass Slides and Cover Slips
Standard glass slides are the final stage for most histological and cytological preparations. Paired with cover slips, they protect specimens and allow for clear viewing under the microscope. Adhesive-coated slides may be used for special stains or IHC procedures.
6. Histology Stains (e.g., H&E)
Stains such as hematoxylin and eosin (H&E) are indispensable for highlighting tissue structures. Other special stains (PAS, Masson’s trichrome, etc.) are used for specific diagnostic purposes. Quality stains ensure consistent coloration and interpretability.
7. Slide Storage Boxes and Filing Systems
Proper archiving of slides and paraffin blocks is essential for long-term case tracking and future review. Durable storage boxes, slide trays, and filing cabinets maintain order and protect samples from damage.
8. Fixatives (e.g., Formalin)
Fixatives preserve tissue morphology by stabilizing proteins and preventing degradation. 10% Neutral Buffered Formalin is the gold standard for most surgical specimens. Pre-filled containers improve safety and convenience.
9. Labeling Materials (Labels, Printers, Markers)
Accurate labeling of cassettes, slides, and containers is critical for sample traceability and error prevention. Thermally printed labels, solvent-resistant markers, and barcode systems streamline identification.
10. PPE & Biosafety Supplies
Though often overlooked, personal protective equipment (gloves, lab coats, goggles) and items like biohazard bags, sharps containers, and spill kits are indispensable for ensuring lab safety and regulatory compliance.
Conclusion
While advanced instruments drive modern pathology labs, consumables form the backbone of everyday operations. Stocking the right materials not only ensures smooth workflow but also supports diagnostic accuracy and lab accreditation. Labs that invest in quality consumables—from paraffin wax to PPE—demonstrate a commitment to safety, precision, and excellence in patient care.
