Roche and Abbotts lab based blood tests claim close to 100% sensitivity (ability to detect positive samples as positive) and greater than 99% specificity (ability to detect negative samples as negative).
Does that mean the disease is far less contagious than previously thought or are Sweden's control measures effective (or both)?A recent study in Stockholm showed just 7% had antibodies by the end of April. They were expecting 30%.
I think the Guardian article is only considering the rapid tests.Good explanation of it here but it's from the 8th May with the Biomednomics test. (More recent tests may be more reliable)
How to understand Covid-19 antibody testing in 10 steps
Inaccuracies in the testing, such as false negatives and false positives, are potentially harmfulwww.theguardian.com
For those who suspect that they had it
18% false negatives
13% false positives
If these figures are accurate, the Guardian article needs to be rewritten.

It could be both. It knocks the herd immunity approach back, they were expecting a much higher infection rate.Does that mean the disease is far less contagious than previously thought or are Sweden's control measures effective (or both)?
The lab based test cost are being estimated between $25-$50. This would only be the cost of the test. Additional cost would be taking the blood sample, transport etc. Costs would go down as volume goes up.I for one would like to know if I already caught the Covid-19.
I would pay for my own antibody test. Provided that it was under €10 or €20. And not €150 or more like the official test up to now.
I was abroad in early January and had a bit of a cough and sniffles when I came home for a couple of days. I was blaming it on bad beer.
If I get a positive result, what are the implications?
