    Turnaround Times:

    Samples are usually processed and completed processed within one business day after receipt. Typically, you will receive a report one business day after the lab receives your sample.

    Transport Medium:

    We will supply you with saline.Simply call the office to place your order. This media should remain at room temperature. A biopsy accidentally placed in formalin, if only for a few seconds, will be unusable for IF and under no circumstances will a biopsy be processed. Please keep this in mind before sending a sample accidentally placed in formalin, as it could read falsely negative. Please note: All samples placed in saline MUST BE processed within 48 hours. If the 48 hour timeline cannot be accomodated, the specimen must be refrigerated until it can be submitted to the lab.

    Taking the Biopsy:

    A punch biopsy is preferred (3-4 mm); however, shave and excision biopsies are also acceptable for processing. Biopsies for immunobullous diseases are best if taken from non-lesional skin that is 1 to 2 cm away from a lesion. Make sure the biopsy is fully immersed in saline before tightening the vial lid. The biopsy should be kept at room temperature until it reaches the laboratory.

    Shipping Instructions:

    You can send your samples via USPS mail or overnight delivery. Please ensure the lid or stopper is tightened and then place in a biohazard bag. It is of the utmost importance that the lid on the vial or stopper on the tube is tightened before being shipped. Include the completed requisition form making sure it is in a separate area of the biohazard bag. Please get the biopsy to our lab within 48 hours of placing in saline.

    Courier Instructions:

    If the sample is to be delivered by courier, it is not necessary to package in anything but a biohazard bag. The courier should take the sample to Suite 160 in BioScience One. The samples should not be left anywhere else.
