What is the required frequency for WBC for staff with a 14-day bioassay frequency?

The required frequency for a white blood cell (WBC) count in relation to a 14-day bioassay frequency aligns with the need for regular monitoring of staff who may be exposed to hazardous materials. A quarterly WBC count ensures that any potential changes in the staff's health, particularly related to exposure levels, are detected in a timely manner, without going too long between assessments. This frequency strikes a balance between adequate monitoring and resource management, allowing for healthcare providers to effectively track any trends in health related to exposure risks. Regular quarterly assessments can help in identifying issues early and can guide timely interventions if an abnormal trend is noticed. In contrast, a monthly count could lead to unnecessary resource use, while biannual or annual counts might not provide sufficient monitoring to ensure staff safety under the risk of exposure.
