Analytical Methods (Based on this test)

01

DNA Analysis

  • Species identification through mitochondrial DNA and/or nuclear DNA analysis, including COI, cytochrome b, 12S/16S rRNA and other appropriate genetic markers.
02

Chemical and Material Analysis

  • Analysis of material composition using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Fluorescence Spectroscopy (XRF) and other relevant techniques to determine the chemical and elemental composition of the sample.
03

Imaging and Microscopic Analysis

  • Observation and recording of microstructural features and morphological characteristics using high-resolution photography and microscopy.

Identification Conclusion

The analyzed sample is identified as Red Fox (Vulpes vulpes).

The results from DNA analysis, chemical composition analysis (FTIR and XRF), and microstructural characteristics are consistent with the biological characteristics of Red Fox (Vulpes vulpes). No evidence indicates that the sample originates from any other species.
