A recent study published by the Annals of Allergy, Asthma, and Immunology (ACAAI), pointed out, in a study of 109 people tested, that skin prick tests are not 100 percent reliable. In the study, participants were subjected to oral food challenges prior to skin testing in which 50 percent of individuals had no reaction. It was also discovered that blood tests were not full-proof even though they measure the presence of IgE antibodies to specific foods. These results are not surprising given that 50 to 60 percent of tests result in false-positives.
This occurs for several reasons:
It would seem, therefore, that more reliable tests are needed which brings me back to the lab. Today, blood tests are commonly interpreted using Enzyme-Linked Immunosorbent Assay (ELISA) despite a high incidence of false-positives. ELISA is affordable, straightforward, and provides effective testing results when used in conjunction with a person’s medical history. However mass spectrometry is more effective in detecting allergens due to its sensitivity, ability to correspond to unique allergen peptides, and its multi-allergen capabilities. Yes, mass spec is more expensive, but because of their versatility and sensitivity, you get a swift ROI while reducing those pesky false positives. You can learn more about Mass Spectrometry Myths in one of my previous posts.

With the launch of the ZenoTOF 8600 system, EAD has taken a significant leap forward in becoming a routine tool for metabolomics and lipidomics workflows. Building on the foundation laid by the ZenoTOF 7600 system, the 8600 system introduces enhanced sensitivity, function speed improvements, and multimodal capabilities that make EAD more practical and scalable for daily use. This blog explores how these advancements are transforming EAD from a specialized technique into a robust and accessible solution for high-throughput structural analysis, enabling researchers to unlock deeper insights with greater efficiency.
In your lab, time is not just a resource. It’s a necessity and every moment counts. Yet, unplanned downtime can disrupt this delicate balance. Even a brief interruption can set your team back in multiple ways.
In a recent webinar, which is now available on-demand, Holly Lee powerful strategies to tackle complex residue testing. From boosting throughput to fine-tuning method sensitivity, Holly shared key ways to maximize performance across large pesticide panels.
