The NPA test is a measure of the antibacterial strength of the honey as compared to the antiseptic - phenol. It was the original grading test that the UMF level was based off. While the UMF level today is based off the 4 factor test, the NPA level still matches the UMF number; the same way it did historically. The level of MGO (the compound that creates the antibacterial properties) is directly correlated to NPA level in the honey.

Note:
We are NOT members of the UMF Association, and we do not claim to label our products with the UMF™ trademark. This graph is here to help you compare our results against the UMF four-factor test. Joining UMF requires a $40,000 joining fee plus ongoing annual royalties; those costs are typically recovered through higher retail prices to the customer. As a small business, we don’t believe that’s good value.
Instead, we invest in testing. We measure everything UMF™ requires — and more, going further by checking 20+ markers of quality and authenticity. We share those results openly so you can make an informed choice.

Sprays & Residues
Tutin Residue
A tiny insect called the passion vine hopper feeds on the tutu plant and excretes a substance – honeydew – onto the branches and leaves of the plant. When honeybees feed on this honeydew, it can contaminate their honey.
Tutin Compliance: PASS
Tutin Result: <0.01
Herbicides
Testing to confirm honey does not have any herbicide residue
Result: PASS
Glyphosate: <0.010
Glufosinate: <0.010
Aminomethyl phosphonic acid: <0.010
Herbicides (Trace)
A second test to confirm the honey does not have any herbicide residue
Result: PASS
Glyphosate: <0.010
Glufosinate: <0.010
Aminomethyl phosphonic acid: <0.010
