## Cost Per Reportable Test Formula

The following equation is used to calculate the Cost Per Reportable Test.

CPRT = TC / TRT

- Where CPRT is the cost per reportable test ($/RT)
- TC is the total cost of supplies
- This should include costs for supplies on all reportable and unreportable tests

- TRT is the total number of reportable tests

To calculate the cost per reportable test, divide the total cost of supplies by the total number of reportable tests.

## What is the Cost Per Reportable Test?

Definition:

Cost per reportable test (CPT) is a metric that reports the cost associated with each test ordered by a laboratory. CPT is calculated by dividing the total cost of the tests ordered in the lab by the number of tests reported to CLIA. The lower the CPT, the more efficient and cost effective the lab’s testing process is.

## How to Calculate Cost Per Reportable Test?

Example Problem:

The following example outlines the steps and information needed to calculate Cost Per Reportable Test.

First, determine the total cost of supplies for all tests. In this example, the cost of supplies is $1,000.00.

Next, determine the total number of reportable tests performed. In this case, the total number of reportable tests is found to be 200.

Finally, calculate the cost per reportable test using the formula above:

CPRT = TC / TRT

CPRT = $1000 / 200

CPRT = $5.00 / reportable test
