What is this test?

This is not a specimen-based laboratory test. It is a reporting measure that calculates the difference in recorded healthcare personnel, or HCP, cases between the current and previous reporting periods.

Why might I need this test?

Public health and workplace surveillance programs may use this measure to track changes in cases among healthcare personnel and assess the need for infection-control or occupational-health measures.

How is the test performed?

Case totals from the current reporting period are compared with totals from the preceding period. The difference may be expressed as a count, percentage change, or trend, depending on the reporting system.

How do I prepare for the test?

No laboratory preparation is required. Interpreting the result requires accurate and complete case information from both the current and previous reporting periods.

Frequently asked questions

What does HCP mean in this test name?
HCP stands for healthcare personnel. The measure concerns reported cases involving this population rather than an individual blood or urine test.
Is this a laboratory test I need to prepare for?
No. It is a comparison of case totals collected during two reporting periods, so there is no specimen collection or special preparation.
What does a change in the result mean?
A positive difference means more cases were reported in the current period, while a negative difference means fewer were reported. Changes in testing and reporting practices can also affect the comparison.
