Deferred revenue

Deferred
revenue, which is a contract liability, consists of billings or cash received for services in advance of revenue recognition and is recognized as revenue when all the Company’s revenue recognition criteria are met. As of December 31, 2024
and June 30, 2025, the deferred revenue balance was $2.8 million and $2.2 million, respectively, all of which is considered short-term. For the six months ended June 30, 2024 and 2025, revenue recognized from deferred revenue at
the beginning of the period was $2.3 million and $1.5 million respectively. The decrease in deferred revenue balances as of December 31, 2024 as compared to June 30, 2025 is attributed to the timing of contractual payments for
testing and consulting services and timing of delivery of the clinical test results and services.
