STP.168 Clinical Study Protocol Parakeet

The Parakeet is a lateral flow cassette designed to aid in the detection of parathyroid gland by identifying tissue with parathyroid hormone levels \> 60 pg./ml in a fine needle aspirate specimen. The FNA specimen of the target tissue is combined with running fluid and deposited into the sample well of a lateral flow cassette. Lateral flow occurs and the Test Line begins to darken within minutes if PTH is present in quantities \> 60 pg./ml. At 5 minutes, a full visualization of the TL is done. A negative test (\< 60 pg./ml of PTH in the sample) shows darkening of the Control Line only. Absence of Control Line development indicates a defective test kit. INTENDED USE The Parakeet Rapid Parathyroid Testing Kit is an immunoassay lateral flow cassette intended to detect qualitative differences in extracellular concentration of parathyroid hormone in excised samples suspected of being parathyroid glands as an adjunct to current clinical methods, including histopathology, to locate the parathyroid glands. INDICATIONS FOR USE The Parakeet Rapid Parathyroid Testing Kit is indicated for use in adult patients where location of the parathyroid glands is medically necessary, such as in patients undergoing parathyroidectomy for Hyperparathyroidism.
