The Mycometer-air technology was recently (2011) verified by United States Environmental Protection Agency through the ETV programme. Linearity between enzyme activity measured as fluorescence and the number of spores was well documented(R2 = 0,997). The reproducibility was determined by collecting 8 parallel samples and have them analyzed by two analysts (4 each) using two different analytical instruments. An RPD of 5.3% was found. This is an exceptionally low variability, unprecedented in any other method available for measuring mould in air.
The Mycometer-air technology has also been documented through peer revieved papers in international journals.
Two new studies have shown that high levels of NAHA enzyme activity (as is measured with the Mycometer-air method) correlate to health issues.
- High levels of NAHA activity in air samples were found in homes of subjects with sarcoidosis, particularly among those with recurrent disease.

- A correlation was seen between NAHA activity and Nocturnal Asthma.

- A Swedish study showed that higher levels of NAHA enzyme activity were found in air samples from buildings with mould damage compared to control buildings.
