I can’t recommend this company enough. I had a small issue and the boss rang me, that in itself made my problem go away... as the gesture was enough. Suffice go to say everything was handled properly and with common sense (quite a rare commodity) and more

Another supplier let me down by not delivering an urgent quantity of LF tests within the promised 2 business... days.Kirsty was able to save my bacon with an OVERNIGHT delivery to tide us over while we tracked down the original order.I think you can guess where my next major purchase is going to go. Highly recommended and endorsed.Plus the sweeties were much appreciated 🙂read more

Instructions for Use:

A nasal swab sample is collected from the person being tested using the sterile swab within your kit.

Step 1

The swab is then inserted into a bottle that contains 2 ml of buffer solution. The swab containing cell samples should be stirred well and pressed to the bottom of the bottle.

Step 2

The swab should be stirred well and the test cassette removed from the foil packaging.

Step 3

3-4 drops of sample are dripped on to the lateral flow device (LFD). The result will be shown in 15 minutes.
