These work well to test macro nutes

Those kinds of tests could be ok to use if you’ve run them before in soil that performs well and you can compare against the standard results you got last time. I’d say the better thing would be to order a mail-in soil test. I’ve never seen one cost more than $50, with most being around $30. They’re a bit tricky to interpret if you’re not a soil expert, but the guys at Build A Soil have a great video archive of where to get a test done and how to read it.
