1. What is Cost Per Test?

Cost Per Test (CPT) is a healthcare metric that calculates the average cost of performing a single laboratory test. It includes all associated costs such as laboratory equipment, staff salaries, reagents, and overhead expenses divided by the total number of tests performed.

2. How Does the Calculator Work?

The calculator uses the CPT formula:

Where:

• \( CPT \) — Cost Per Test (currency per test)
• \( \text{Total Test Costs} \) — Sum of all laboratory costs (currency)
• \( \text{Tests Performed} \) — Total number of tests conducted (count)

Explanation: This formula provides the average cost for each test performed, helping laboratories understand their cost structure and optimize resource allocation.

3. Importance of CPT Calculation

Details: Calculating Cost Per Test is essential for laboratory management, budgeting, pricing strategies, and identifying opportunities for cost reduction while maintaining quality standards.

4. Using the Calculator

Tips: Enter total test costs in your local currency and the number of tests performed. Ensure both values are positive numbers (costs > 0, tests ≥ 1).

5. Frequently Asked Questions (FAQ)

Q1: What costs should be included in Total Test Costs?
A: Include all direct and indirect costs: laboratory equipment depreciation, staff salaries, reagents, consumables, utilities, maintenance, and administrative overhead.

Q2: How often should CPT be calculated?
A: Monthly calculation is recommended for ongoing monitoring, with quarterly detailed analysis for strategic decision-making.

Q3: What is a good CPT benchmark?
A: Benchmarks vary by test type and region. Compare with industry standards and similar laboratories for meaningful analysis.

Q4: How can we reduce our CPT?
A: Strategies include bulk purchasing, process optimization, automation, reducing test repeats, and efficient staff scheduling.

Q5: Does CPT include quality control costs?
A: Yes, quality control materials and processes should be included in total costs as they are essential for reliable testing.
