Would you kindly decipher this for me, "albumin is less than the lower limit of the analytical range of the method." thank -you?

Low albumin level : Albumin is a type of protein the liver produces. It’s one of the most abundant proteins in your blood. You need a proper balance of albumin to keep fluid from leaking out of blood vessels. It also carries vital nutrients and hormones, & provides your body with the proteins it needs to maintain growth and repair tissue. Low levels may indicate that your kidneys or liver isn’t working correctly.
