New tubes may alter PT results by patient group; hypothesis-generating and should not yet change lab practice.
Does blood collection in new siliconized borosilicate tubes inhibit cold-promoted activation of prothrombin time in normals and patients receiving warfarin?
New siliconized borosilicate collection tubes differentially inhibit cold-promoted activation of prothrombin time depending on patient status (normal, warfarin-treated, or pregnant).
Palmer et al. (1985) studied this question.
