The technique of measuring thrombin generation with fluorescent substrates: 4. The H-transform, a mathematical procedure to obtain thrombin concentrations without external calibration

In the original article “The technique of measuring thrombin generation with fluorescent substrates: 4. The H-transform, a mathematical procedure to obtain thrombin concentrations without external calibration” by Hemker et al. in the January 2009 issue of Thrombosis and Haemostasis an error occured on page 175 in the right column, line 2. Instead of “the scaling factor for the non-defibrinated plasma therefore is 31.2/6.53=4.78 nm/AU. The scaling factor for the non-defibrinated plasma is 11.6 AU/min.” this phrase should read “the scaling factor for the non-defibrinated plasma therefore is 31.2/6.53=4.78 nm.min/AU. The scaling factor for the defibrinated plasma is 11.6 nm.min/AU.” The authors apologise for this error.
