What are the limitations of the Assure hCG Test Kits?
If a urine specimen is too dilute (i.e., low specific gravity) it may not contain representative levels of hCG. If pregnancy is still suspected, first morning urine should be obtained from the patient 48-72 hours later and tested. Immunologically interfering substances such as those used in antibody therapy treatments may invalidate the test result See the package insert for further limitations.
