Tissue Biopsy Specimen Requirements

Prenatal kits are available by contacting our Clinical Coordination team directly at 617-209-2090.

The following tissue biopsy types are preferred: skin, muscle, lung, liver, spleen, pancreas. Formalin-Fixed Paraffin-Embedded (FFPE) tissue is NOT accepted.

Tissue biopsy samples should be placed in a cup, covered completely with phosphate buffered saline (PBS) and sealed with parafilm.

Cups must be labeled with the individual’s name and date of birth, which must match the name and date of birth on the test order. Unlabeled or mislabeled samples will not be accepted.

Tissue biopsy samples should be shipped immediately after being collected, with a cold pack. If immediate shipping is not possible, tissue biopsy samples may be refrigerated. Tissue biopsy samples should never be frozen.

Every prenatal kit includes a pre-paid FedEx return label to Variantyx. For any questions about returning a sample, please contact our Clinical Coordination team directly at 617-209-2090.
