![]() Osmolality is normally used for more detailed analysis, but USG remains popular for its convenience. decreased concentration of solutes in urine) may be associated with renal failure, pyelonephritis, diabetes insipidus, acute tubular necrosis, interstitial nephritis, and excessive fluid intake (e.g., psychogenic polydipsia). A value >1.025 indicates normal concentrating ability. Hypovolemic patients usually have a specific gravity >1.015.ĭecreased specific gravity (hyposthenuria, i.e. What is normal urine specific gravity 1.005 to 1.030 (normal specific gravity) What does a specific gravity of 1.025 mean Specific gravity is usually 1.010-1.025 (normal range: 1.003-1.030) and highest in the morning. In neonates, normal urine specific gravity is 1.003. A specific gravity greater than 1.035 is consistent with frank dehydration. increased concentration of solutes in the urine) may be associated with dehydration, diarrhea, emesis, excessive sweating, urinary tract/bladder infection, glucosuria, renal artery stenosis, hepatorenal syndrome, decreased blood flow to the kidney (especially as a result of heart failure), and an excess of antidiuretic hormone caused by the syndrome of inappropriate antidiuretic hormone secretion. Increases in specific gravity (hypersthenuria, i.e. ![]() COMPOSITION OF URINE Volume 600-2000ml Specific. In adult humans, normal specific gravity values range from 1.010 to 1.030.Īdults generally have a specific gravity in the range of 1.010 to 1.030. INTRODUCTION Urine analysis is one of the most commonly performed laboratory tests in clinical picture. The third reason for low specific gravity is renal failure, which results in a fixed specific gravity between 1.007 and 1.010. The concentration of the excreted molecules determines the urine's specific gravity. The body excretes some of these waste molecules via urination, and the role of the kidney is to concentrate the urine, such that waste molecules can be excreted with minimal loss of water and nutrients. One of the main roles of the kidneys in humans and other mammals is to aid in the clearance of various water-soluble molecules, including toxins, toxicants, and metabolic waste. Abnormal results are generally those below. Normal results in adults generally range from 1.010 to 1.020. For background on kidney function, see Renal function. Results vary slightly by lab instruments and methods.
