Chem Chek will be closed for in-office testing this Friday, 3/31/23. We hope everyone has a great weekend!

Tuesday 3/21/23 we have several tests scheduled at school districts in the morning and will have a delayed opening until about 10:30am or 11:00am. We apologize for any inconvenience this may cause and look forward to fulfilling your testing needs as expeditiously as possible.

We will not be open for in-office testing all day Wednesday 3/15/23 and will close at noon Thursday 3/16/23.

Whew! It's going to be a Monday all day! We have scheduled onsite tests throughout the day and will be tag-teaming the office testing. 9:30am - 11:00am should be fine. We will not be there between 11am and 1pm. Opening again from 1pm - 2:30pm.

3/1/23 It's raining and that usually leads to accidents. We will be out of the office at 10:30 and should be back by noon. We are very sorry for the inconvenience!

Into every life, a little rain must fall... and with the rain comes accidents. We will probably be a little late opening the office. We are all out post accident testing.

Yay! We have the "all is fine" from the COVID tests. We just have the regular nasty cold that's been going around. We will be open in the morning, at about 9:30.

We will remain closed today and will update this afternoon regarding office hours tomorrow.

CLOSED TODAY AND MONDAY DUE TO COVID EXPOSURE. Out of concern for your health and ours - check back for updates.
