Welcome to XXXXXXX and thanks for your query.
Urine analysis may be either dipstick or microscopy.
The value mentioned is detected by dipstick and needs to be quantified by doing a microscopy to look for RBC
If the RBC in urine is less than 3 in number, there is no need to worry, unless you are symptomatic.
If microscopy is not done, it is wise to do and decide further the further course of action.
Please let me know the microscopy result and the normal value of the test done already ( normal values are usually mentioned in brackets)
