Revenue Growth and Oncology Performance:
- Guardant Health reported revenue growth of 21% year-over-year to $203 million in Q1 2025.
- The oncology business contributed significantly, with revenue increasing by 20% year-over-year to $151 million.

Oncology Product Adoption and Cost Efficiency:
- Oncology volumes grew by 25% year-over-year to approximately 59,000 tests in Q1.
- Guardant360 test volumes accelerated, and Guardant Reveal showed strong growth.
- Cost reductions and improved reimbursements, especially for Medicare Advantage and commercial payers, contributed to the positive financial outlook.

Screening Business and Market Potential:
- Shield testing generated $5.7 million in revenue in Q1, driven by approximately 9,000 tests.
- Shield received Additional Medicare Local Coverage Determinations (ADLT) status, resulting in a price increase to $1,495.
