An analytical device for predicting a subject's whole blood analyte concentration based on the subject's interstitial fluid (ISF) analyte concentration includes an ISF sampling module, an analysis module and a prediction module. The ISF sampling module is configured to sequentially extract a plurality of ISF samples from a subject. The analysis module is configured to sequentially determining an ISF analyte concentration (e.g., ISF glucose concentration) in each of the ISF samples, resulting in a series of ISF analyte concentrations. The prediction module is configured for storing the series of ISF analyte concentrations and predicting the subject's whole blood analyte concentration based on the series by performing at least one algorithm. A method for predicting a subject's whole blood analyte concentration based on the subject's interstitial fluid analyte concentration includes extracting a plurality of interstitial fluid (ISF) samples from a subject in a sequential manner and sequentially determining an ISF analyte concentration in each of the plurality of ISF samples to create a series of ISF analyte concentrations. The subject's blood analyte concentration is then predicted based on the series of ISF analyte concentrations by performing at least one algorithm. |
