(A‐D) Limit of detection of Hydragel 5 VW Multimers (H5VWM) using diluted normal plasma. H5VWM densitometry from left low molecular weight multimers (LMWM) to right high molecular weight multimers (HMWM) with peaks 1‐3 LMWM, 4‐7 intermediate molecular weight multimers (IMWM), and above 7 HMWM. Normal quality control sample is indicated by a solid black line and test samples in blue. The multimer image is depicted in the top right of each (A), von Willebrand factor antigen (VWF):Ag of 20 IU/dL densitometry LMWM 15.8%, IMWM 38%, HMWM 46.2%. (B) VWF:Ag of 15 IU/dL densitometry LMWM 19%, IMWM 35.8%, HMWM 45.2%. (C) VWF:Ag of 10 IU/dL densitometry LMWM 32%, IMWM 23.4%, HMWM 44.6%. (D) VWF:Ag of 5 IU/dL densitometry LMWM 30.8%, IMWM 23.4%, HMWM 45.8%
