Limitations
A key limitation for this test is that no frozen samples or samples not separated properly can be used. Additionally, non-EDTA plasma specimens or samples showing gross icterus are not acceptable, which might affect the accuracy or viability of the test results, necessitating re-collection under appropriate conditions.
