Study Notes
Tissue Processing
- Tissue processing refers to the preparation of tissue samples for examination, involving a series of steps to preserve and maintain the tissue's structure and integrity.
Advantages of Fixed Impregnated Tissues
- Fixed impregnated tissues offer the advantage of enhanced visibility and contrast, allowing for better analysis and identification of cellular structures and features.
Importance of Proper Labeling
- Proper labeling of tissues is crucial to ensure accurate identification and tracking of samples, avoiding mix-ups and incorrect diagnoses.
- Labels should include essential information, such as the patient's name, specimen type, and date.
Numbering System for Specimens
- The numbering system for each specimen in most laboratories serves to uniquely identify and distinguish individual samples, facilitating efficient storage, retrieval, and tracking.
Labeling with Ordinary Ink
- Labeling should not be done using ordinary ink, as it can fade or run over time, compromising the accuracy and reliability of the labeling process.
