WHAT
This
document details the procedure for rounding of analytical results.
1.0 why
It is the policy of the ABC Pharmaceuticals that a written
procedure shall be followed for the rounding off analytical results in
order to make the results more meaningful and understandable.
2.0 when
This procedure is
to be applied at the time of recording the analytical data in the test
protocols/ reports.

4.0 PROCEDURE
4.1 rounding of dissolution and uniformity of cantant results
4.1.1
In case of dissolution and uniformity
of content values, rounding of analytical results shall be done in first
decimal place.
4.1.2
If the digit of second decimal
place is smaller than five, it shall be eliminated and preceding digit shall be
unchanged.
4.1.3
If the digit of second decimal
place is five or greater than five, it shall be eliminated and preceding digit
shall be increased by one.
4.2 rounding of impurity AND LOD OF WORKING STANDARDS results
4.2.1
In case of impurity and LOD values,
rounding of analytical results shall be done in third decimal places.
4.2.2
If the digit of fourth decimal
place is smaller than five, it shall be eliminated and preceding digit shall be
unchanged.
4.2.3
If the digit of fourth decimal
place is five or greater than five, it shall be eliminated and preceding digit
shall be increased by one.
4.3 rounding of OTHER results
4.3.1
In case of other tests,
rounding of analytical results shall be done in second decimal places.
4.3.2
If the digit of third decimal
place is smaller than five, it shall be eliminated and preceding digit shall be
unchanged.
4.3.3
If the digit of third decimal
place is five or greater than five, it shall be eliminated and preceding digit
shall be increased by one.
