INDIANA (WEHT) – Indiana officials are making several changes to its testing operations amid a surging demand for rapid tests.

Across the state, testing sites have extended their hours to meet the growing number of people seeking test results after the holiday travel season. Effective immediately, rapid tests at state and local health departments will only be available to those who are 18 and younger, and to those who have symptoms and are over the age of 50.

Officials say the change is necessary because of the shortage of rapid tests across the country. Currently, Indiana uses roughly fifty-thousand rapid tests a week. Indiana is only guaranteed eleven-thousand a week. Any appointments made before the change will be honored, but no other appointments will be accepted unless an individual meets the criteria.
