4 and June 30, 2025, respectively. Our cash and cash equivalents consist of cash held in
sweep accounts, checking accounts, and lock-box accounts. The cash and cash equivalents are primarily for working capital purposes. Such interest earning instruments carry a degree of interest rate risk. Our
financing arrangement with Western Alliance Bank subjected us to variable amount of interest on the principal balance outstanding, the debt was extinguished in 2024. Our debt facility with Oberland Capital is at a fixed rate of interest. The effect
of a hypothetical 10% change in interest rates would not have had a material impact on our financial statements for the years ended December 31, 2023 and 2024 or the six months ended June 30, 2025.

Inflation risk

We do not believe that inflation has had a material

Our inability or failure to fully offset any such higher costs could harm our business, financial condition, and results of operations.

Foreign currency exchange rate fluctuations

Our operations are currently conducted almost entirely in the United States as international markets contribute less than 1% of
our revenue. If we choose to expand internationally, our results of operations and cash flows may become subject to fluctuations due to changes in foreign currency exchange rates. In periods when the U.S. dollar declines in value as compared to the
foreign currencies in which we incur expenses, our foreign currency-based expenses will increase when translated into U.S. dollars. In addition, future fluctuations in the value of U.S. dollar may affect the price at which we sell our tests outside
the United States. To date, our foreign currency risk has been minimal.

Critical accounting estimates

We prepare our financial statements in conformity with GAAP. The preparation of financial statements in conformity with GAAP required certain estimates and assumptions
to be made that may affect our financial statements. Accounting policies that have a significant impact on our results are described in Note 2 to our financial statements included elsewhere in this prospectus. The accounting policies discussed in
this section are those that we consider to be the most critical. We consider an accounting policy to be critical if the policy is subject to a material level of judgment and if
