We give you an extra day to collect samples
Our lab is open Saturday 9-12pm. We accept samples every day but Sunday! These hours give you the ability to collect samples whenever it is convenient for you. You can collect samples on Friday, mail them in (using USPS only), and you’ll have the important results you need by Monday or Tuesday.
