Why do samples have dark areas on CellaVision Laboratory Equipment?
- AAngela WadeSep 12, 2025
If you observe dark areas of stain or other artefacts in samples analyzed by CellaVision Laboratory Equipment, it may be because the blood smear was not completely dry when it was stained. Ensure that the blood smear is completely dry before staining it. Other potential causes include dirty slides, so use clean slides. Inadequate washing can also cause this issue, so increase the wash step. Finally, a stain may be forming precipitate in the solution, so filter the stain.
