Meaning of the used abbreviations:
BLD ‑ Blood, UBG ‑ Urobilinogen, BIL ‑ Bilirubin, PRO ‑ Protein,
NIT ‑ Nitrite, KET ‑ Ketone, GLU ‑ Glucose, SG ‑ specific gravity of
the urine (density), LEU – Leukocytes
17.5.2 Precision
The precision was evaluated by using the commercially
available control solution Medi‑Test Control, manufactured by
MACHEREY‑NAGEL, Dueren, Germany. This Control is used for
daily routine system check of the URYXXON
®
500 urinalysis system.
It is available as a 2 level set (Medi‑Test Control N = level 1 (N):
negative‑normal, Medi‑Test Control P = level 2 (P): positive values).
Repeatability and reproducibility amount to 100 % in all cases.
The results are summarized in the following table.
