A modified blood glucose test strip reduces the risk of contamination when it is used with a blood glucose meter. The modified strip has adhered to its top surface a protective shield that is preferably cut from a sheet of transparent plastic. The shield permits access to the sample-receiving surface of the strip, but prevents contamination of the meter by the user, because it covers a part of the meter that adjoins the strip when the strip is installed in the meter. Similarly, the shield protects a user from contacting a potentially contaminated area of the meter. The modified strip finds particular advantage in a hospital or other setting where several persons may use the same meter.
