What is the normal range of bacteria in urine?
On microscopy, there should be no bacteria in uninfected urine, so any bacteria on Gram-stained urine under microscopy is highly correlated to UTI.
A good urine sample with greater than 5 to 10 WBC/HPF is abnormal and highly suggestive of UTI in symptomatic patients.
Urine cultures are not needed in uncomplicated UTI..
What does a borderline urine test mean?
A borderline result is generated by some assays when the hCG level is between 5 and 25 mIU/mL. Samples reported as borderline are considered indeterminate, and clinicians should request a repeat test within 48 to 72 hours or obtain a quantitative serum hCG.
Why is water absorption test done?
Water absorption is used to determine the amount of water absorbed under specified conditions. Factors affecting water absorption include: type of plastic, additives used, temperature and length of exposure. The data sheds light on the performance of the materials in water or humid environments.
What does abnormal urine test mean?
A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine. Abnormal urinalysis results may point to a disease or illness.
What does a normal urinalysis look like?
“Normal” urine can be clear or cloudy. Substances that cause cloudiness but that are not considered unhealthy include mucus, sperm and prostatic fluid, cells from the skin, normal urine crystals, and contaminants such as body lotions and powders.
What is specific gravity mean?
relative densitySpecific gravity, also called relative density, ratio of the density of a substance to that of a standard substance. …
What should not be found in urine?
Red blood cells, white blood cells, protein, glucose and amino acids should be kept in the blood. These components should not be present in urine. water and salt is needed by the body and will remain in the blood.
Why is specific gravity important?
4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid’s characteristics compared to a standard, usually water, at a specified temperature.
What is specific gravity used for?
The term “Specific Gravity” (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2oF (4oC), because this temperature allows water to assume its maximum density.
What does a specific gravity of 1 indicate?
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. … If the relative density is exactly 1 then the densities are equal; that is, equal volumes of the two substances have the same mass.
How do you increase specific gravity?
To increase the specific gravity of juice: Add table sugar to increase the gravity. To calculate the amount needed, take an initial gravity reading, then subtract that from the specific gravity you wish to begin with. The difference will determine approximately how much sugar to add (use column on right).
What does SG stand for on a urine test?
Urine specific gravity is a laboratory test that shows the concentration of all chemical particles in the urine.
Is specific gravity 1.015 normal?
Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.
What is the normal pH range of urine in humans?
The normal values range from pH 4.6 to 8.0. The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories.
What is specific gravity and how is it measured?
Specific gravity is the density of a material at a certain temperature divided by the density of water at a certain temperature; the reference temperature is usually 20 degrees Celsius. Pycnometers measure volume. However, having weighed the sample, you can obtain density by dividing the volume into the sample mass.
How many types of urine tests are there?
Five standard urine tests can be used to examine the different components of urine. Two of them can also be done at home, whereas the other three can only be done in a lab.
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. A value >1.025 indicates normal concentrating ability. A value >1.035-1.040 suggests possible contamination, very high levels of glucose, or recently received low-molecular-weight dextran or high-density radiopaque dyes.
What is normal specific gravity for urine?
The normal range for urine specific gravity is 1.005 to 1.030.
What does high specific gravity in urine mean?
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 does a high specific gravity mean?
High specific gravity suggests that the urine is too concentrated. Conditions that cause high specific gravity include: dehydration. diarrhea or vomiting resulting in dehydration.
What should a normal urinalysis look like?
Normal urine can vary from pale light yellow to a dark amber color. Highly concentrated urine has a darker yellow appearance. This may be seen in patients who are volume depleted. In contrast, dilute urine has a lighter yellow appearance.
What does a specific gravity of 1.020 mean?
Urine specific gravity is a measure of the ratio of the density of urine to the density of water. Urine specific-gravity measurements normally range from 1.002 to 1.030. 5. The NCAA selected a urine specific-gravity measurement of ≤1.020 to indicate euhydration. 4.
Is specific gravity of 1.005 normal?
In general, normal values for specific gravity are as follows: 1.005 to 1.030 (normal specific gravity) 1.001 after drinking excessive amounts of water. More than 1.030 after avoiding fluids.
