Intended Use
The Nichols Advantage® Chemiluminescence Intact Parathyroid Hormone Immunoassay is intended for use with the Nichols Advantage Specialty System for the quantitative determination of intact parathyroid hormone in serum, EDTA plasma, and heparinized plasma. Measurements of parathyroid hormone levels are used in the differential diagnosis of hypercalcemia (abnormally high levels of calcium in the blood) and hypocalcemia (abnormally low levels of calcium in the blood) resulting from disorders of calcium metabolism. Measurements of intact parathyroid hormone levels are also used as an aid in monitoring therapeutic intervention of secondary hyperparathyroidism that frequently occurs in chronic kidney disease. Assay results should be used in conjunction with other clinical data to assist the clinician in making individual patient management decisions.
Device Description
The Nichols Advantage Intact PTH assay contains sufficient reagents for 100 tests. The assay is a two-site chemiluminometric assay specific for Intact PTH.
More Information

Not Found

No
The summary describes a standard immunoassay kit and system for measuring parathyroid hormone levels. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML applications in medical devices. The description focuses on the chemical and analytical aspects of the assay.

No
The device is an in vitro diagnostic immunoassay that measures parathyroid hormone levels, which is used for diagnosis and monitoring, not for treating a condition.

Yes

The device is intended for the quantitative determination of parathyroid hormone levels, which are used in the differential diagnosis of hypercalcemia and hypocalcemia, and as an aid in monitoring therapeutic intervention of secondary hyperparathyroidism. This explicitly states its use in diagnosis and monitoring, which are functions of a diagnostic device.

No

The device description clearly states it is an "assay" containing "reagents" for a "two-site chemiluminometric assay." This indicates a chemical-based laboratory test, which is a hardware-dependent process, not a software-only device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it's for the "quantitative determination of intact parathyroid hormone in serum, EDTA plasma, and heparinized plasma." This involves testing biological samples in vitro (outside the body).
  • Purpose: The measurements are used in the "differential diagnosis of hypercalcemia and hypocalcemia" and as an "aid in monitoring therapeutic intervention." These are diagnostic and monitoring purposes, which are key functions of IVDs.
  • Device Description: It describes an "assay," which is a common term for a laboratory test performed in vitro.
  • Predicate Device: The mention of a predicate device (K962598) is common for IVDs seeking regulatory clearance, indicating it's being compared to a previously approved IVD.

The information provided clearly aligns with the definition and characteristics of an In Vitro Diagnostic device.

6. Comparison to Predicate Device:

  • Heparinized plasma was added to the specimen matrix for Intact PTH testing. .
  • Use of 6 different blood collection tubes was compared for similarities and differences for . Intact PTH testing, and results of comparative testing yield essentially equivalent results.
  • Specimen stabilities have been included in the new labeling for EDTA plasma, . Heparinized plasma, and serum testing.
  • New labeling and scientific references supporting use of Intact PTH testing in patients . with chronic kidney diseases were added.

7. Similarities:

  • There is no change in technology from the original device cleared under K962598. .
