How To Read An Asbestos Sample Certificate / Report

So you've had your samples tested and your much anticipated certificate of results has landed in your inbox. Due to UKAS requirements certificates can be somewhat confusing to someone who's never seen one before. But don't worry its actually really simple to understand once you know the basics.

1) Check the certificate is yours

The first thing to do before getting into the nitty gritty is to make sure the certificate you have received is meant for you and has your details written in top section.

We've highlighted in red the two areas to check.

Firstly is the site address correct? this should match the address where you took the sample from (and the one you wrote the sample submission form before sending off your samples).

Secondly check that the Site Ref No matches your sample reference number, which you obtained when registering your kit.

If anything doesn't look right then contact customer support before continuing any further! Otherwise lets carry on and see what our results mean.

2) Check your results

So now that we know we have the right certificate in our hands its time to see what the results where. We've highlighted in red the area we are going to take a look at next. This is a table showing each of the samples you submitted along with the results from the lab.

So check this list of samples and make sure its the same as what you submitted. Each sample will be numbered (1 through to 10) next to each sample will be the Sample Location and Fibre Type Detected. 

In the certificate pictured here you can see Sample 1, was from a Board in Bedroom 1, and the fibre type detected was "Amosite/Chrysotile". In this example Asbestos HAS been found. Although it doesn't explicitly say "ASBESTOS FOUND" it does say which asbestos fibres where found. In this example it was Chrysotile & Amosite fibres.

Here are the different types of asbestos fibres: (Chrysotile, Amosite, Crocidolite, Tremolite, Anthophyllite). If your results have any of these next to them it means that asbestos was found! In fact the only time you should consider the result negative (no asbestos found) is if you see N.A.D.I.S in the fibre type detected column. NADIS stand for "No asbestos detected in sample".

Did your results come back positive?

3) Don't confuse the KEY

In the footer of the certificate is the final sign off from the lab analyst, and theres also a grey box with a heading of "KEY". Which is then followed by NADIS - No Asbestos Detected In Sample. 

This is not to be confused with your results. This is simply a KEY telling you what NADIS means.

And so thats a wrap! Its a simple as that.
