Thyroxine values for dried blood spots on paper may be low if the paper has been long exposed to high ambient temperature and (or) humidity and (or) to sunlight. Low values are associated with poor extractability of the red color from the spots. We recommend appropriate precautions for such samples.
如果纸张长期暴露于高温和(或)高湿度环境以及(或)阳光下,纸上干血斑的甲状腺素值可能会偏低。低值与血斑红色素的提取性差有关。对于此类样本,我们建议采取适当的预防措施。
