What does it mean to have high specific gravity?
Specific gravity. Normal: 1.005–1.030 footnote 1. Abnormal: A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
What causes elevated specific gravity in urine?
The first and most common reason for an increase in urine specific gravity is dehydration. The second reason for a high specific gravity is an increased secretion of anti-diuretic hormone (ADH). ADH causes increased tubular water re-absorption and decreased urine volume.
Does higher specific gravity mean heavier?
The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water. Minerals with a specific gravity under 2 are considered light, between 2 and 4.5 average, and greater than 4.5 heavy.
What does specific gravity mean on urine test?
Urinary specific gravity (SG) is a measure of the concentration of solutes in the urine. It measures the ratio of urine density compared with water density and provides information on the kidney’s ability to concentrate urine. A urinary specific gravity measurement is a routine part of urinalysis.
Is specific gravity of 1.010 normal?
Normal results in adults generally range from 1.010 to 1.020. Abnormal results are generally those below 1.010 or above 1.020. In patients with certain kidney diseases, USG doesn’t vary with fluid intake and is called a fixed specific gravity.
Does high specific gravity mean dehydration?
Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be. High urine specific gravity can indicate that you have extra substances in your urine, such as: glucose.
Does specific gravity affect weight?
Specific gravity is the density of a substance divided by the density of water. Once you know density, you know mass per unit volume, and from that you can determine the weight.
Does water increase specific gravity?
Density is defined as the mass per unit volume of a substance. Water has a density of 1 kg/l at 4°C. When the specific gravity is defined based on water at 4°C, then the specific gravity is equal to the density of the liquid….4.6. 2 Specific Gravity.

Is high specific gravity in urine bad?
The normal specific gravity ranges from person to person. Your urine specific gravity is generally considered normal in the ranges of 1.005 to 1.030. If you drink a lot of water, 1.001 may be normal. If you avoid drinking fluids, levels higher than 1.030 may be normal.
Is nitrite in urine normal?
Having nitrates in urine is normal and not harmful. However, having nitrites in your urine could mean you have an infection.
