UREA NORMAL RANGE MANUAL

UREA NORMAL RANGE MANUAL

For the adult male, the normal range is 0.6 to 1.2 mg/dl, or 53 to 106 μmol/L by the kinetic or enzymatic method, and 0.8 to 1.5 mg/dl, or 70 to 133 μmol/L by the older manual Jaffé reaction. The normal serum creatinine ( sCr) varies with the subject's body muscle mass and with the technique used to measure it. In contrast, the rugged rancher who eats in excess of 125 g protein each day may have a normal BUN of 20 mg/dl. Her higher glomerular filtration rate (GFR), expanded extracellular fluid volume, and anabolism in the developing fetus contribute to her relatively low BUN of 5 to 7 mg/dl. A BUN of 15 mg/dl would represent significantly impaired function for a woman in the thirtieth week of gestation. The range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion. The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dl, or 1.8 to 7.1 mmol urea per liter. The BUN, then, is roughly one-half (28/60 or 0.446) of the blood urea. In Europe, the whole urea molecule is assayed, whereas in the United States only the nitrogen component of urea (the blood or serum urea nitrogen, i.e., BUN or SUN) is measured. Both are relatively small molecules (60 and 113 daltons, respectively) that distribute throughout total body water. Creatinine is the product of muscle creatine catabolism. Urea is the primary metabolite derived from dietary protein and tissue protein turnover. JAVMA 188:449.Urea and creatinine are nitrogenous end products of metabolism.

Of course you should distinguish the enhancement of the value of BUN in physiologic with pathologic situation due to kidney disorders.ġ. The value of SC in this study was the same as others. In this study the value of BUN had got the average of 70mg/dl in both female and male Persian cats that it is different with other studies in other cats that were between 15 to 45mg/dl. There wasn't any significant different for BUN and SC in male and female groups (p<0.05). The value of SC was between 0.636 to 3.272 mg/dl with the average of 1.45 mg/dl.

In female cats, it was between 50.4 to 90.5 mg/dl with the average 70.25mg/dl. Estatic analysis of these data showed the average of 71.36 mg/dl. The value of BUN in male cats was between 50.92 mg/dl to 91/8 mg/dl. The results analyzed with SPSS soft were and samples due to male and female groups were assessed by T test. BUN and SC were detected on serum by spectrophotometric method with wave length of 520nm. This investigation was carried out on 90 mature Persian cats (45 male and 45 female) that were elected randomly, after confirmation of their clinical and paraclinical health, blood samples were taken after 18 to 24 hour of fasting. Books & VINcyclopedia of Diseases (Formerly Associate)įor survey of kidney function BUN (blood urea nitrogen) and SC (serum creatinine) are very important and since there is no normal value of these factors in Persian cats, this study have been done.VINcyclopedia of Diseases (Formerly Associate).
