For HCPs
Confirm Your Cases with No-Cost Genetic Testing
Details on the DetectHypopara™ Program, sponsored by BridgeBio, offering no-cost genetic testing across 26 hypoparathyroidism-associated genes. This includes eligibility criteria, the easy three-step ordering process, updated 2025 best practice recommendations, and information on complementary genetic counseling for patients.
Low Calcium, Low PTH? These Clues Can Point to ADH1
An overview of ADH1, a distinct yet underrecognized genetic form of hypoparathyroidism. Learn how gain-of-function CASR gene variants dysregulate calcium homeostasis, which symptoms to watch for, why diagnostic delays are common, and how genetic testing can confirm a diagnosis when surgery isn't the cause.
Get Started With the DetectHypopara™ Program
Understand the role of genetic testing in diagnosing and managing hypoparathyroidism.
Annotated Guide to a Genetic Test Report
A sample report is provided and details on findings are highlighted, including:
- Results (negative, indeterminate, positive)
- Sequence variant(s)
- Name of condition, if known
- Journal articles to find more information
- Recommendation for additional testing for family members and genetic counseling
CASR=calcium-sensing receptor; HCP=healthcare professional; PTH=parathyroid hormone.
