Including deliberate rows of empty cores (holes filled only with paraffin) is a practical troubleshooting aid, especially in manually constructed arrays where orientation can be challenging. When manually transferring hundreds of tiny, visually similar cores from a punch needle to specific holes in a grid, it is very easy to lose one's place—to skip a row, double-punch a hole, or become misaligned. An empty row acts as a clear, visual landmark. When looking at the finished block or the first test section, the histotechnologist or researcher can immediately spot the blank row. By locating this known landmark on the physical block and comparing it to the master grid map, they can instantly re-orient themselves and verify the correct placement of all surrounding tissue cores. It's a simple but effective method of error-checking that adds robustness to the manual construction process, ensuring the critical link between physical position and patient data remains accurate.
