However, established cut-off values for postnatal follow-up differ between countries and are based on little evidence.
The nanostructured immunosensors show a storage stability of at least 25 days, a linear range between 0.014 and 15 ng mL−1, and a LOD of 4 pg mL−1, which is 100 times lower than the established cut-off value for heart failure (HF) diagnosis.
This enables the application of previously established cut-off values for MBF with 15O-water PET-CT also in PET-MR studies [10].
Using the previously established cut-off value of 2.3 mL/g/min to decide between normal and pathological stress MBF [10], on a subject-based level, five subjects had pathological MBF (at least one segment with MBF <2.3 mL/g/min) in the PET-CT study and all of these subjects also had pathological MBF in the PET-MR-based analysis.
We abstained from reporting the ACTH levels, since COR has been demonstrated to be the best parameter for analyzing DEX/CRH test results and since most established cut-off criterions are related to COR levels but not ACTH concentrations.
Our established cut-off titers were applied in the seroepidemiological surveillance to estimate the infection rate in different groups of the Thai populations after subsidence of the first epidemic wave.
The reporter strain containing a copy of the sphingomyelinase 2 promoter, Psph2 (P2G) was also strongly induced by the conditions tested, above an established cut-off, whereas the non-virulence factor promoter control, from the lipL41 lipoprotein gene, was not.
Long-term follow up of DTC can safely be based on serial Tg-on measurement with a sensitive Tg assay and additional diagnostic tests should be performed only when Tg-on rises above an established cut-off level.
The scale does not have an established cut-off value.
However, established cut-off values were used for the plasma glucose and HbA1c values.
