Technical News Attention all Melatonin customers BÜHLMANN Melatonin assays discontinued, and manufacturing and sales are now transitioned to NovoLytiX GmbH, CEO Dr. Jacky Weber, info@novolytix.ch.
Starting in early 2020, BÜHLMANN evaluated transfer options for its melatonin assay portfolio including the Melatonin RIA assays (RK-DSM2-U and RK-MEL2-U), the Direct Saliva Melatonin ELISA (EK-DSM-U) and the 6-Sulfatoxymelatonin ELISA (EK-M6S-U). As a result, BÜHLMANN Laboratories AG and Swiss based NovolytiX GmbH signed a transfer agreement in July 2020. Both parties agreed, NovolytiX GmbH will take over all melatonin immunoassay kits as of January 1, 2021
Email us at info@buhlmannlabs.com or call (844) 300-979 if you or lab has NOT been contacted about this transition &/or you would like more information. Announcing new Health Canada license for the following BÜHLMANN assays - 1. fecal Elastase assay - BÜHLMANN fPELA® turbo

Food allergy is a growing public health burden in children and adults all over the world. In some countries, up to 10% of infants are affected by food allergies (Loh et al., 2018). Relatively few foods like cow milk, egg, wheat, soy, nuts, fish, and shellfish account for the majority of allergies. Nevertheless, every food at any age can cause allergic reactions, from mild symptoms such as itchiness up to serious reactions including anaphylaxis…..

“In conclusion, the MONAS study demonstrates that the BAT is effective in diagnosing peanut and tree nut allergy in a real-world setting, and may be useful in reducing the number of resource-intensive OFCs needed. Additional prospective studies to investigate the ability of the BAT to reduce OFCs are required.” Flow CAST® 2) Garnett, E., Pagaduan, J., Rajapakshe, D., Tam, E., Kellermayer, R., & Devaraj, S.

“The newly FDA-cleared fCal Turbo assay, with the Calex cap for sample extraction, represented a much more rapid and facile workflow for our laboratory than referring samples for analysis by ELISA. We determined that the fCal Turbo assay on the Vitros 5600 analyzer offered excellent performance relative to ELISA, was reproducible, and was not excessively prone to analytical interference. We anticipate that it will be a useful tool for identification of IBD in our patient population.” BÜHLMANN fCAL® turbo 3) Isak Östlund , Mårten Werner & Pontus Karling (2020).

“The IBDoc® is a simple tool to use and high satisfaction is found among IBDoc® users. IBD patients should be adequately informed and trained on the use of this test. FC home tests are an additional value for e-health approach in IBD patients.

IBDoc®, patient care during COVID-19 [HC Class 3 cleared in Canada, not available for sale in USA]
How does BÜHLMANN help the IBD patient care during the COVID-19 pandemic? In a recent article the task force summarized a list of “Do’s” and “Don’ts” in IBD management.
“Do’s for general clinical practice:
With IBDoc® and the CALEX® Cap Collection Set, BÜHLMANN provides ideal tools for patients to easily measure their calprotectin levels directly at home or send in the stool sample in a safe and convenient way to the laboratory.
IBDoc® can be easily combined with patients self-assessing symptoms through ePRO either app-based, web-based or via communication with the HCP directly. As highlighted in the ECCO taskforce paper, it has been shown as effective as a lab test (Heida et al., 2017) and can provide a rapid assessment of the disease activity while staying at home. Several countries have implemented and successfully tested a combined fCAL home monitoring and ePRO tool e.g. Walsh et al. 2019 or McCombie et al. 2019.
