Specific gravity and disease. Adults generally have a specific gravity in the range of 1.010 to 1.030. Increases in specific gravity (hypersthenuria, i.e. increased concentration of solutes in the urine) may be associated with dehydration, diarrhea, emesis, excessive sweating, urinary tract/bladder infection, glucosuria, renal artery stenosis ...
It is not possible for the kidneys to produce urine with a specific gravity greater than 1.040 [40] but such readings can occur in urine that contains high-molecular weight substances, such as contrast dyes used in radiographic imaging. [38] Specific gravity is commonly measured with urine test strips, but refractometers may also be used. [41]
Isosthenuria refers to the excretion of urine whose specific gravity (concentration) is neither greater (more concentrated) nor less (more diluted) than that of protein-free plasma, typically 1.008-1.012. [1] Isosthenuria reflects damage to the kidney's tubules or the renal medulla . A closely related term is hyposthenuria, where the urine has ...
A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample. The test can often be read in as little as 60 to 120 seconds after dipping, although certain tests require longer. Routine testing of the urine with multiparameter strips is ...
Reference ranges for urine tests are described below: Measurement. Lower limit. Upper limit. Unit. Urinary specific gravity. 1.003 [1] [2] 1.030 [1] [2]
Urine normally has a specific gravity between 1.003 and 1.030. The Urine Specific Gravity diagnostic test is used to evaluate renal concentration ability for assessment of the urinary system. [ 13 ] Low concentration may indicate diabetes insipidus , while high concentration may indicate albuminuria or glycosuria .
Diabetes insipidus. Diabetes insipidus ( DI) (arginine vasopressin disorder), alternately called arginine vasopressin deficiency (AVP-D) or arginine vasopressin resistance (AVP-R), [ 5] is a condition characterized by large amounts of dilute urine and increased thirst. [ 1] The amount of urine produced can be nearly 20 liters per day. [ 1]
In healthy humans with restricted fluid intake, urine osmolality should be greater than 800 mOsm /kg, while a 24-hour urine osmolality should average between 500 and 800 mOsm/kg. [citation needed] Urine osmolality in humans can range from approximately 50 to 1200 mOsm/kg, depending on whether the person has recently drunk a large quantity of ...
