Thank you, Leslie. Despite changes to our technology staffing model over the last year, we have kept a keen eye on organizational efficiencies and growth opportunities fueled by technological advancements. The success of the Next-Day Quotes Program has relied heavily on our sales team's ability to quickly and accurately determine the feasibility of a customer's request. This matchmaking is fueled by the capabilities and inventories provided by our global network of suppliers and powered by iSpecimen proprietary technology. Beyond our emphasis on proprietary technology, enhancing the acumen of our sales, marketing, operational and site development teams through deliberate business intelligence strategies has significantly amplified our capacity to preempt and respond to customer demand. This proactive approach has assisted in the markedly improved conversion of quotes to purchase orders discussed earlier, setting new benchmarks for performance.
I would like to now turn the discussion to our revenue enhancement initiative. Our embedded coordinator program remains a key priority for our long-term growth and has been impacted by the rollout of our supplier network refresh program. We currently have embedded coordinators at 3 sites, each of which have very strategic growth plans tied to them. These sites have all moved over to the Next-Day Quotes Program, due to the support of our embedded coordinators. Our goal is to place embedded coordinators in additional sites as we work in partnership with suppliers on our supplier network refresh program.
Our cancer sequencing initiative remains an important longer-term growth driver. Now that we have created inventory of mutation characterized formalin-fixed, paraffin-embedded FFPE cancer tumor tissues. There is significant value in having access to these biospecimens due to the fact that they are extremely difficult to find and hold significant potential to support cancer research. As we had mentioned in our call at year-end, we established a pipeline of new business opportunities in the fourth quarter of 2023. That pipeline now totals approximately $1.5 million from new and existing customers. Through our internal due diligence, we have 27 confirmed new orders across 65 ongoing projects.
As we stated previously, several outstanding projects that had not resulted in a win were the direct result of not having found the exact markers being requested. Given the pricing and value proposition, this program continues to be well accepted by our customers, and we will provide further updates as we are still working to upgrade the targeted marketing plan for this program.
I will now turn to our financial results. For the quarter ended March 31, 2024, revenue was approximately $2.3 million compared to approximately $3 million for the quarter ended March 31, 2023. The decrease in revenue for the first quarter of 2024 was primarily due to a decrease of 3,388 specimens or 39% in specimen count from 8,629 specimens in the 3 months ended March 31, 2023 to 5,241 specimens in the quarter ended March 31, 2024. The effect of the decrease in specimen count was partially offset by a change in the specimen mix, which caused the average selling price per specimen to increase by $95 per specimen or 28% from approximately $342 per specimen in the 3 months ended March 31, 2023 to $437 per specimen in the 3 months ended March 31, 2024.
Cost of revenue decreased by approximately $147,000 or 13% from approximately $1.1 million for the 3 months ended March 31, 2023 to approximately $1 million for the 3 months ended March 31, 2024. Although there was a 39% decrease in the number of specimens accessioned during the quarter ended March 31, 2024. Over the same prior year period, the average cost per specimen increased by $58 per specimen or 44% from $133 per specimen for the quarter ended March 31, 2023, to $191 per specimen for the quarter ended March 31, 2024.
Technology expenses increased by approximately $78,000 or 9% to approximately $900 and $12,000 for the quarter ended March 31, 2024, from approximately $834,000 for the same period in the prior year. The increase was related to increases in amortization of internally developed software of approximately $99,000, professional fees of approximately $11,000 and general operating expenses of approximately $1,000, which were partially offset by decreases in headcount and payroll and related expenses of approximately $33,000.
Sales and marketing expenses decreased by approximately $296,000 or 31% to approximately $660,000 for the quarter ended March 31, 2024, from approximately $962,000 for the same period in the prior year. The decrease was primarily attributable to decreases in payroll and related expenses of approximately $217,000, external marketing expenses of approximately $95,000 and general operating expenses related to sales and marketing of approximately $20,000, which were partially offset by an increase in advertising and promotion expense of approximately $36,000.
General and administrative expenses increased approximately $286,000 or 16% from approximately $1.8 million for the quarter ended March 31, 2023, to approximately $2.1 million for the quarter ended March 31, 2024. The increase was attributable to increases in professional fees of approximately $329,000, taxes and insurance of approximately $267,000 and bad debt expense of approximately $45,000, which were partially offset by decreases in compensation costs of approximately $250,000, general operating expenses of approximately $78,000, depreciation and amortization of approximately $23,000 and utility and facility expenses approximately $4,000.
As of March 31, 2024, iSpecimen had approximately $2.1 million of cash and cash equivalents and approximately $466,000 of available-for-sale securities with maturities ranging from 1 to 6 months for a combined total of approximately $2.6 million compared to a cash balance of $5 million as of December 31, 2023. For the first quarter of 2024, $1.2 million of our $2.5 million of cash use was attributable to onetime charges, which included consulting and legal fees, franchise tax compliance and fees associated with our aftermarket offering. As I mentioned earlier, without these onetime charges, our burn rate for the quarter would have been approximately $1.2 million or a little over $400,000 per month, which is significantly improved from where we were a year ago.
Also, as we mentioned in our last earnings call, on March 5, 2023, we entered into an aftermarket offering agreement. We may issue and sell shares of common stock from time to time with an aggregate offering price of up to $1.5 million through our shelf registration statement. We may also seek additional funding through public equity and other sources to fund further capital investments or for general corporate purposes.
Reductions in our workforce in 2023 and continuing through the first quarter of 2024 resulted in an estimated reduction in monthly compensation costs of approximately 41% in the 3 months ended March 31, 2024, when compared to the same period in the prior year, which was possible after streamlining operations and rationalizing resources to focus on key market opportunities. While we have taken steps to reduce the current number of suppliers in our network, as just discussed, our long-term strategy is to add additional customers and suppliers to increase revenues through our revenue enhancement projects and our Next-Day Quotes Program, while continuing to reduce and manage expenditures to improve our financial position and ensure continued funding of operations.
This concludes our prepared remarks. Now I'd like to open the call for questions. Operator, please go ahead.
