What usually happens next

Nothing to act on; there's no sign of inflammation.

When a CRP can read wrong

Some labs report CRP in mg/dL rather than mg/L: 0.3 mg/dL is 3 mg/L. Any recent infection, injury, hard exercise or vaccination raises it for a week or two.

Questions

Is a CRP of 0.5 mg/L normal?

A CRP of 0.5 mg/L is under 1 mg/L, the lowest of the heart-risk bands the AHA and CDC use for high-sensitivity CRP. The usual range is under 3 mg/L in most healthy people; many labs flag above 5 or 10.

Is a CRP of 0.5 mg/L high?

Under 1 mg/L is low, 1 to 3 average and over 3 raised. Over 10 usually means an infection or active inflammation rather than long-term heart risk.
