The approach comprises
- a unique calibrator system
- an automated and standardized measurement and data analysis process
- internal quality controls
- and many other actions.
This overcomes individual spectrometer variability and other contributors to variation to achieve reproducible results even on different devices.
Nuclear magnetic resonance (NMR), is a physical phenomenon based on the magnetic interaction of atomic nuclei with each other, with the electron shell of the molecule and with external magnetic fields. NMR is utilized in medicine and several scientific and technical fields of application.
NMR spectroscopy is widely used in the field of biomedical research. On the one hand it is used to elucidate the structure and dynamics of nucleic acids, amino acids, peptides and proteins as well as to decipher their interaction with active ingredients. Structure elucidation by NMR can be done directly in solution - in contrast to X-ray structural analysis.
High-resolution NMR spectroscopy is also a key technology in the field of metabolomics/metabonomics research. The metabonomics approach uses the entirety of metabolites to draw conclusions about physiological or pathophysiological metabolic states.
Many complex questions in various biological systems can be answered using this approach. To date, metabolomics has mainly been used in research. In the future this powerful methodology and therefore NMR spectroscopy is bound to find wider application, particularly in laboratory diagnostics.
In the field of laboratory diagnostics, NMR techniques are being used increasingly successfully to determine the concentrations of metabolic products (metabolites) in body fluids such as plasma, serum or urine.

AXINON® is a modular system that supports different tests for in vitro diagnostic (IVD) or research use.
The AXINON® Software supports the measurement of samples prepared using AXINON® reagents on a qualified NMR spectrometer. In conjunction with integrated test-specific software modules for in vitro diagnostic (IVD) or research use provided by numares HEALTH, the AXINON® Software enables the simple and parallel quantification of a variety of analytes which can support the diagnosis, prevention, monitoring or treatment of disease.
The AXINON® Software is intended for professional use only.
AXINON® supports the analysis of human samples using nuclear magnetic resonance spectroscopy (NMR).
Yes, AXINON® is a platform solution that has been specially designed to simultaneously support different tests.
In the daily routine, AXINON® can be operated by a single person. Only for maintenance is a second person required.
Each trained laboratory employee can operate the system. Previous knowledge in the field of NMR spectroscopy is not required.
With manual pipetting, sample preparation takes about 45 minutes for about 100 samples. Thanks to the 96 tube format of the racks, liquid handling can be easily automated.
The measurement time of an analytical sample takes, depending on the specimen type, test and device, a few minutes.
At full capacity, more than 300 serum samples can be measured within 24 hours.
With manual sample preparation, the hands-on time is approximately half a minute per sample.
The operation of the software requires only about 2 minutes per analytical run (up to 93 analytical samples).
AXINON® is very easy to use and requires only a few operator interactions. The system is designed for minimal hands-on time and maximum walk-away time. At full loading of the sample changer, up to 465 samples can be measured without the user having to interact with the test system. Even at full capacity of about 300 samples a day, the operator need only spend 15 minutes interacting with the device and software. Manual pipetting requires approximately 2.5 h for sample preparation.
The software automatically creates a result file. Moreover, the results can be exported to Excel format, saved as a report in PDF format or printed directly.
In recent years, there has been increasing evidence that not only the cholesterol itself, but also its "packaging" in lipoprotein particles is critical to the risk of cardiovascular disease. It has been shown, that especially small LDL particles with higher density, so-called small dense LDL (sdLDL), are associated with an increased risk .
Thus, a more accurate picture of lipoproteins would help to uncover an otherwise undetected cardiovascular risk and countermeasures could be introduced in good time, e.g. through a change in lifestyle or medication.
The patient does not necessarily have to fast prior to blood sampling. However, for better comparability of blood fats, it is recommended to use fasting samples.
Blood samples should be collected aseptically by qualified personnel using approved blood sampling techniques . numares recommends the S-Monovette® blood serum collection tubes made by Sarstedt. Please note that BD Vacutainer® SSTTM tubes containing separating gel are not suitable for lipoFIT®.

numares recommends the Sarstedt S-Monovette® serum tubes. Please note that BD Vacutainer® SSTTM tubes containing separating gel are not suitable for lipoFIT®.
The S-Monovette® Serum (Sarstedt) has been tested and approved for use with AXINON® lipoFIT®. Any other tubes must be approved.
A minimum of 700 μl of serum is required for the analysis.
Serum specimens should be stored as follows:
- 2-8°C: up to 4 hours
- -20°C and below: up to one month
- -70°C and below: extended storage
Please avoid repeated freezing and thawing.
Specimens are to be shipped frozen at -10°C to -30°C.
Precision measurements were conducted according to an internal protocol on the basis of guideline CLSI EP5-A2 (1). Reproducibility was assessed at three study sites. Repeatability (within-run imprecision), intermediate precision (between-runs and between-days imprecision) and reproducibility (between-sites imprecision) were determined in serum pools at three concentrations.
Depending on the respective parameter, coefficients of variation ranged below 4.5% (within-run), below 4.9% (between-run), below 4.0% (between-day) and below 5.1% (between-site). The mean total imprecision between 3 different systems was 3.7%, demonstrating an overall excellent precision.
