I have never heard of this test kit and have no idea of it's reliability.
This does NOT mean it's NOT reliable, but in the US, we recommend only the home testing kits which have been approved by the FDA. "Fujibio" was not on that list.
I wish I knew of a link for you to research this kit, but if there are HIV/AIDS clinics in the Philippines, that's where I would start.
Sorry I couldn't be of more help.
