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.
How soon can you do pg pee test after HCG trigger? I did my HCG trigger shot about 12 days ago (currently 11 dpiui), and I'm dying to take a home pg test. My RE wants me to wait until this Friday (17 days past trigger, 16 dpiui) before doing a blood test. I think that the home pg test will measure HCG also, so I understand I shouldn't test too soon, don't want to get a false positive, but c'mon, 17 days?!?
