Comparison of the performance on Ebola antigen detection between the current FET biosensor and other published works/commercial products. For limit of detection, some studies utilized pfu/ml as a measure of virus concentration, while other studies including ours utilized ng/ml for protein concentration. There is no direct conversion between the two units.
