2025 represents the first full year for Shield IVD, where very meaningful volume and revenue generation exceeds our expectations. We have significantly expanded the commercial team and established impactful strategic partnerships to meet the growing demand for a high-performing, blood-based screening option. Importantly, this execution has directly driven strong financial performance, both accelerating our top-line growth and strengthening our path to profitability. Turning to top-line performance on slide four, we delivered $281 million of revenue in the Q4, representing 39% year-over-year growth, and $982 million of revenue or 33% year-over-year growth for the full year.
This exceptional performance reflects continued broad-based growth across our oncology screening and biopharma and data businesses. Taking a closer look at our oncology business in slide five, oncology revenue increased 30% to $190 million, and oncology volumes grew 38% to approximately 79,000 tests in the Q4. Together, these drivers will continue to catalyze very strong growth in our oncology business. Reveal continues to be our fastest-growing product, reflecting growing demand for tissue-free MRD.
Turning to slide 9 to take a closer look at our Reveal data pipeline. Shifting gears to our biopharma and data business in slide 11, we delivered another year of strong performance, with revenue growing 18% year-over-year to $210 million in 2025. We are a leader in companion diagnostics, with 25 approvals to date across the U.S., Japan, and Europe, and a robust pipeline of ongoing CDx programs. We delivered $35 million of Shield testing revenue in Q4, driven by approximately 38,000 tests, which was a meaningful step-up compared to 24,000 tests in Q3.
