Abstract
Articles and methods for preparing a surface for obtaining a patient sample, such as blood, are generally provided. In some embodiments, the methods involve wiping a surface of skin of a patient in preparation for obtaining a sample (e.g., a blood sample) from the patient. In some embodiments, the methods involve wiping the surface of the skin with two or more wipes. For instance, the surface of the skin may be wiped with a first wipe comprising a surfactant and a second wipe comprising an antiseptic solution. Advantageously, the use of a first wipe including a surfactant followed by a second wipe may remove a higher amount of certain contaminants (e.g., proteins, bacteria, viruses) from the surface of the skin as compared to the use of a single wipe or by hand-washing alone.
