When our courier picks up samples,the freezer temperature will be checked and the reading <br /> recorded on the Chain of Custody record. Alternatively,sodium bisulfate and methanol preserved vials <br /> can be used to collect the samples. <br /> Can 1 continue using the sodium bisulfate and methanol vials? <br /> Yes. Our preference is that sample freezing be utilized,but the use of other options is acceptable. <br /> Do I have to ship my samples to the lab? <br /> if freezing will not be initiated by you within 48 hours,then samples must either be delivered to the <br /> laboratory by courier such as UTS or Federal Express,or picked up by our courier to allow the freezing to <br /> be initiated within 4S hours. If samples are going to be shipped on Friday for delivery on Saturday, <br /> arrangements must be made with the laboratory. <br /> For further information,please contact us at 630-778-1200.
