Abstract: The aspects of the disclosed embodiments relate to method for determining a likelihood of an inflammatory gastrointestinal tract disease. The method includes diluting a biological sample of a human subject and contacting it with 8-anilinonaphthalene-1-sulfonic acid as modulating agent and further with a reagent, said reagent comprising a peroxidase enzyme and a label selected from a europium chloride and terbium chloride. The sample is incubated and excited, and the time-resolved luminescence signal of the label in the sample is measured. If the luminescence signal is at least 112% higher than for a control sample from a human so subject without of an inflammatory intestine disease, an increased likelihood of an inflammatory intestine disease of the human subject is determined.

Abstract: The present disclosure relates to a method for detecting a prostate cancer related biomarker, including contacting the diluted sample with a modulating agent selected from a group consisting of sodium; 3-hydroxy-4-[(2-hydroxynaphthalen-1-yl)diazenyl]naphthalene-1-sulfonate, sodium; 3-hydroxy-4-[(1-hydroxynaphthalen-2-yl)diazenyl]-7-nitronaphthalene-1-sulfonate, triisopropylsilane, and iron(III) chloride, and a luminescent label to obtain a measurement sample. Then, the measurement sample is incubated for a period of time and excited thereafter. Time-resolved luminescence signal of the label in the measurement sample is measured, leading to an increased likelihood of prostate cancer of the human subject if the luminescence signal is at least 50% higher than for a control sample from a human subject without prostate cancer.
