The primary advantages of tissue processing, specifically routine manual tissue processing, are its reliability and inexpensive nature.
While other methods of tissue processing exist, the manual method, despite being more time-consuming (approximately 21-24 hours), offers distinct benefits that have maintained its prevalence for over a century. Let's break these advantages down:
-
Reliability: Routine manual tissue processing has a long-established track record. The consistent, stepwise approach to dehydration, clearing, and infiltration has proven to be a dependable method for preparing tissue specimens for microscopic examination. The controlled environment and direct oversight throughout the process contribute to the reliable outcome.
-
Cost-Effectiveness: Compared to automated systems or more advanced technologies, manual tissue processing is generally less expensive. The equipment required is minimal, and the operational costs are lower due to reduced energy consumption and maintenance needs. The simplicity of the process also reduces the risk of equipment malfunction and associated repair costs.
In summary, the enduring popularity of manual tissue processing lies in its proven reliability and its affordability, making it a practical choice for many laboratories, especially those with limited resources.
