building a sales force to market our products and services. We expect to incur substantial net losses through at least 2024 as we further develop and commercialize our diagnostic technology. We also expect that our selling, general and administrative expenses will continue to increase due to the additional costs associated with market development activities and expanding our staff to sell and support our products. Our ability to achieve or, if achieved, sustain profitability is based on numerous factors, many of which are beyond our control, including the market acceptance of our products, competitive product development and our market penetration and margins. We may never be able to generate sufficient revenue to achieve or, if achieved, sustain profitability.
We are subject to concentrations of revenue risk and concentrations of credit risk in accounts receivable.
We have had several customers who, from time to time, have individually represented 10% or more of our total revenue, or whose accounts receivable balances individually represented 10% or more of our total accounts receivable.
For the years ended December 31, 2023 and 2022, one and no customers individually represented 10% or more of our total revenue, respectively. We expect to maintain ongoing relationships with our customers, however, the loss of, or significant decrease in demand from, any of our top customers could have a material adverse effect on our business, results of operations and financial condition.
At December 31, 2023, one customer accounted for approximately 13% of our total accounts receivable and at December 31, 2022, one customer accounted for approximately 12% of our total accounts receivable. The business risks associated with this concentration, including increased credit risks for these and other customers and the possibility of related credit loss write-offs, could negatively affect our margins and profits. Additionally, the loss of any of our top customers, whether through competition or consolidation, or a disruption in sales to such a customer, could result in a decrease of the Company’s future sales, earnings and cash flows. Generally, we do not require collateral or other securities to support our accounts receivable and while we are directly affected by the financial condition of our customers, management does not believe significant credit risks exist at December 31, 2023.
We have been, and may continue to be, subject to costly litigation.
We have been, and may continue to be, subject to legal proceedings. Due to the nature of our business and our history of insufficient capital resources to pay our obligations on a timely basis, we may be subject to a variety of regulatory investigations, claims, lawsuits and other proceedings in the ordinary course of our business. The results of these legal proceedings cannot be predicted with certainty due to the uncertainty inherent in litigation, including the effects of discovery of new evidence or advancement of new legal theories, the difficulty of predicting decisions of judges and juries and the possibility that decisions may be reversed on appeal. Such litigation has been, and in the future, could be, costly, time-consuming and distracting to management, result in a diversion of resources and could materially adversely affect our business, financial condition and operating results.
In addition, we may settle some litigation through the issuance of equity securities which may result in significant dilution to our stockholders.

The commercial success of our diagnostic products, including those we are developing, will depend upon the degree of market acceptance of these products among physicians, patients, health care payers and the medical community and on our ability to successfully market our products.
Our products may never gain significant acceptance in the marketplace and, therefore, may never generate substantial revenue or profits for us. Our ability to achieve commercial market acceptance for our existing and future products will depend on several factors, including:
| ● | our ability to convince the medical community of the clinical utility of our products and their potential advantages over existing diagnostics technology; |
| ● | the willingness of physicians and patients to utilize our products; and |
