✅ Work in hygienic, controlled conditions

This article is part of our Application Protocol Help Centre series🔗 designed to help you get the best performance from your Delvotest® system. By following a unified application protocol across multiple laboratories, you can significantly reduce variability, enhance reliability, and achieve more consistent results. In this article, we focus on the importance of working in a hygienic, controlled environment—one of the core principles for operational success🔗—ensuring that your sample handling processes maintain the highest standards of cleanliness and integrity.

Prevent cross-contamination with clean pipetting practices
For every individual sample, use a new, single-use pipette tip to prevent cross-contamination. If you rely on automatic pipetting machines, incorporate a wash or cleaning step between each sample. Contamination between milk samples can compromise result accuracy, so maintaining these strict pipetting standards is essential.

Maintain a clean and controlled working environment
Always work on a sanitised table, and ensure your hands and equipment are clean before handling samples. By consistently upholding these hygiene standards, you reduce the risk of introducing unwanted contaminants, safeguarding the reliability of your Delvotest® results.

Ensure proper sample homogenisation
Before pipetting, make sure your milk samples are well-homogenised and representative of the batch. This step prevents variations in sample composition, improving consistency and reliability in your outcomes.

Next Steps

In the next article, we’ll explore another fundamental principle—ensuring that you always use validated reference controls—to further enhance the reliability of your testing procedures.
