Stilbestrol dosage

levels Stilbestrol (or diethylstilbestrol, DESare measured to detect and quantify this synthetic estrogenic compound, which is banned inhuman and animal food. Historically used as a growth promoter or hormone treatment, stilbestrol is now strictly prohibited due to its toxicity, carcinogenic potential , and endocrine-disrupting effects.

This analysis helps to ensure regulatory compliance of agri-food products, nutraceutical supplements and environmental matrices (water, soil, effluents).

Analytical methods

The dosage of stilbestrol is carried out by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS), a reference method for the detection of hormonal compounds in trace amounts.

• LC-MS/MS : high sensitivity, molecular specificity, precise quantification down to a few ng/kg.
• Sample preparation: liquid-liquid extraction, solid phase purification (SPE) and validation according to current European standards.

Analyses can follow European guidelines (Regulation EC No. 37/2010) and official ISO and AOAC methods, ensuring full traceability and strict regulatory compliance.

Industrial applications

Stilbestrol analysis is applicable to many sectors:

• Agri-food : detection of synthetic hormone residues in meat, milk, eggs or fish.
• Nutraceuticals and phytotherapy : control of plant raw materials and supplements to exclude any contamination.
• Environment : monitoring of effluents or wastewater to detect the presence of endocrine disruptors.
• Regulatory safety : compliance with REACH, EFSA and EC Regulation 1881/2006 requirements.

Matrices analyzed

• Animal products (meat, milk, eggs)
• Surface water, groundwater, wastewater
• Dietary supplements and plant extracts
• Environmental and biotechnological matrices

Further analyses recommended

For complete control of hormonal compounds and endocrine disruptors, YesWeLab recommends:

• Bisphenol A dosage : detection of a common endocrine disruptor found in packaging.
• Phthalate assay : analysis of plasticizers with hormonal activity,
• SVHC testing – Substances of very high concern : comprehensive screening according to the REACH regulation,
• Nonylphenol assay : monitoring of surfactants with estrogenic potential.
