This is the second time I tested Livzon HCG from Health-NaturalBody. The first time I used a generic pregnancy test strip from Walmart and it failed. This time I used Clearblue. I added 1 cc bac water to the vial and gently mixed. (This gives me 11 doses at 450 ius) I use 1 dose of 450 ius for the preg test. The Clearblue test has a large 'paddle' looking surface to hold in the urine sample... because of this large dry area, I added 1/2 cc of bac water after I squirt the HCG onto it. In less than 1 minute the test showed positive.
Conclusion #1: This HCG from HNB is legit.
Conclusion #2: Why the first preg test failed??? Either because the test kit was a cheap generic or because I didn't add 1/2 cc of water to help 'wash' the sample... although the 'Control' line did appear.
Next month I will re-test the Hucog HCG (from a different source) that previously failed using the Walmart preg test. I will run the generic AND the Clearblue tests with an added 1/2 cc of bac water to try and verify if the Walmart brand test kit is faulty.
I hope this info helps! Feel free to ask me questions.
