An Approach to Include the Cost of Consumables in Biochemistry Analyzer Procurement on the Reagent Rental Model Alleviates Hidden Expenses.

Background: Clinical biochemistry analyzers are essential for diagnosing and monitoring various diseases and conditions. However, the procurement of these analyzers is often based on the initial purchase cost, which does not reflect the total cost of ownership.

Methods: We applied a novel approach to include all hidden costs to run parameters (consumables and accessories) on a cost-per-reportable test (CPRT) basis. Fixed expenses like water purification plant, HIS connectivity, and electricity backup were assumed to be included in the cost per test itself, while the calibration cost was distributed uniformly in the calculation of CPRT itself. This CPRT was taken to compare the financial results of different bids.

Results: The cost per reportable test received after applying our novel approach in maintenance-free reagent rental basis bid was 47.4% lower than the previous cost per test for the purchased equipment.

Conclusion: This substantial decrease in cost with our novel approach reduced laboratory expenses possible with accurate comparison among analyzers with uniform specifications after eliminating the hidden expenses.
