*This panel may be listed as 306b – indicating that the Neoplasia Index is modified for specific use in Lymphoma to improve sensitivity and specificity for that application. All other features remain the same.
Background:
The term “hypercalcemia of malignancy” is routinely used when calcium is elevated and PTH is below normal, and for good reason— this situation is often a result of malignant neoplasia, particularly lymphoma, anal sac adenocarcinoma, or multiple myeloma. However, many other diseases can fall into this category such as granulomatous disease, hyperthyroidism, vitamin D intoxication, and Addison’s disease.
Cancer Panel + Calcemia Panel is a combination that determines if the cause of hypercalcemia is cancer. Often times, this panel is performed in a serial way:
Step 1: Calcemia Panel to determine if the hypercalcemia falls into the hypercalcemia of malignancy range (High Ca, Low PTH).
Step 2: Cancer Panel to determine if cancer is present, and the possible source of elevated calcium.
