I get self test strips from Amazon. But you can get them from other places. Do a search for ‘urinalysis strips’. Prices vary (which is why I get them from Amazon, they seem the cheapest). The best brand is Siemens (or Bayer - they are apparently the same).
If you decide to start self testing this is how you do it:
You need strips that are either 8SG tests or 10SG tests, it doesn’t matter which so long as they test the things I’ve listed below (from Amazon, for some reason the 10SG strips are cheaper than the 8x! See: https://www.amazon.co.uk/Siemens-Multistix-Professional-Reagent-Strips/dp/B002E2OMN8/ref=sr_1_1_a_it?ie=UTF8&qid=1476107271&sr=8-1&keywords=Urinalysis+Siemens )
Start with a clean urine sample (i.e. a fresh sample, so when you’ve just attached a clean leg bag to your SPC or into a clean pot for anyone without an SPC).
Dip the test strip into the wee for a few seconds
Wait up to 2 minutes.
The coloured squares on the side of the canister show you what no infection looks like on the left hand side and go across to the right for a positive test. You read from the bottom up as the time taken for results is in that order. A positive result won’t necessarily be the colour of the square on the far right, maybe just the middle.
What you’re looking for is the results for leucocytes (which indicates inflammation), nitrites and protein (indicating infection), also possibly blood, but obviously there could be other reasons for blood appearing.
If you find you have pale pink leucocytes but nitrites and protein are normal, just drink lots of water through the day and retest the following morning. It’s possible that with an SPC you might find the leucocytes are up a tiny bit occasionally anyway.
When I’ve got a definite positive infection, generally it doesn’t take anything like 2 minutes for the leucocytes to go purple and the nitrites almost instantly go bright pink too.
Obviously, if you self test positive for an infection, you also need to get a sample to your GP to test and prescribe antibiotics.
The other thing to keep in mind is that you must keep the test strips completely dry. So either don’t keep them in the bathroom or keep them in a sealable plastic bag. If they’ve got slightly damp, you can tell by the leucocytes indicator being pink before you start. (So you’d get a false positive for leucocytes)
It sounds more complicated than it is. And it is reassuring if you feel like you might have an infection.
