Abstract:
1. A method for identifying pulmonary embolism in patients, the method comprising the steps of: a) measuring a D-dimer concentration in a blood sample; b) determining whether the measured D-dimer concentration is between 100 and 2000 nanograms per milliliter; c) performing, a respiratory test comprising the steps of: d) outputting an indication, in cases when the measured D-dimer concentration is between 100 and 2000 nanograms per milliliter and the calculated carbox ratio is less than or equal to the carbox ratio threshold in the range of 0.25 and 0.30, that a pulmonary embolism is likely; or e) outputting an indication, in cases when the measured D-dimer concentration is between 100 and 2000 nanograms per milliliter and the calculated carbox ratio is greater than the carbox ratio threshold in the range of 0.25 and 0.30, that additional diagnostic testing is required; or f) outputting an indication, in cases when the D-dimer concentration is not between 100 and 2000 nanograms per milliliter and the calculated carbox ratio is greater than the carbox ratio threshold in the range of 0.25 and 0.30, that a pulmonary embolism is unlikely.
