 Generic abbreviated
 NPU08502 B—Glucose; subst.c.incr.(max. c. minus 0 min c.; proc.) = ? mmol/L
Full result NPU08502 Blood—Glucose; substance concentration increment(maximum concentration minus 0 minimum concentration; procedure) = 6 millimol per litre
Abbreviated result NPU08502 B—Glucose; subst.c.incr.(max. c. minus 0 min c.; proc.) = 6 mmol/L
Written expression The substance concentration increment of Glucose in Mr. Smith’s blood is [6] mmol/L. The measurement is performed according to a procedure defined by the laboratory. The calculation is the difference between the maximum substance concentration and the minimum substance concentration in a specific period of time.
