Effective April 1, 2011, code G0431QW is deleted from the Clinical Laboratory Fee Schedule (CLFS). Code G0431 describes a high complexity test, and should not be reported with a QW modifier; the QW modifier indicates a Clinical Laboratory Improvement Amendments (CLIA) waived test.
If this occurs with insemination or intercourse that is timed correctly, the egg may become fertilized. It is important to remember, however, that the hCG within the trigger shot will stay in your urine for 7 to 10 days so you may get a false positive on a home pregnancy test. Because of this, most doctors will wait at least two weeks to give you a blood test designed to test for hCG levels.
This can lead to false positive readings if the extra hCG hasnât completely left your system yet. For accurate results, be sure to wait 14 days to test for pregnancy if you had a 10,000 IU injection, ten days for a 5,000 IU injection or seven days for a 2,500 IU injection. When using a home pregnancy test, you should always read the results within a specific time frame that is usually about five minutes.
