Abstract
A cap with a venting plug for a biological fluid collection device is disclosed. The venting plug allows air to pass therethrough and prevents a blood sample from passing therethrough. In one embodiment, the venting plug is a porous plug. In one embodiment, the cap includes a venting plug including a carboxymethylcellulose additive. A cap that limits analyte bias due to the interaction of plasma ions with the carboxymethylcellulose by reducing the contact area between the blood and the carboxymethylcellulose additive, e.g., decreasing radius, is also disclosed.
