The specific gravity of the soil solids at the test temperature shall be calculated from the density of the soil solids and the density of water at the test temperature or from the mass of the oven dry soil solids mass of pycnometer, water, and soil solids at the test temperature and mass of the pycnometer and water at the test temperature. The apparatus is comprised of water pycnometer which shall be a stoppered flask, stoppered iodine flask, or volumetric flask balance drying oven thermometer dessicator a system for entrapped air removal which shall be a hot plate or Bunsen burner or a vacuum pump or water aspirator insulated container non-corrosive smooth surface funnel pycnometer filling tube with lateral vents sieve and blender with mixing blades. Procedures for moist specimens such as organic soils, highly plastic fine grained soils, tropical soils, and soils containing halloysite and oven-dry specimens are provided. Soil solids for these test methods do not include solids which can be altered by these methods, contaminated with a substance that prohibits the use of these methods, or are highly organic soil solids, such as fibrous matter which floats in water. Results of all analytes will be reported, and the provider should decide if recollection is needed.These test methods cover the determination of the specific gravity of soil solids passing a sieve by means of a water pycnometer. For midstream urine collection instructions refer to Health Facts for you:Ī comment will indicate high levels of SEC. Clean catch (midstream) urine collection may reduce the possibility of contamination. SEC may indicate the possibility of other contaminants such as bacteria. **** Squamous Epithelial Cells (SEC), present in a urine specimen likely enter from sites distal to the bladder. The presence of bacteria is not necessarily indicative of urinary tract infections. Higher levels will be reported as PRESENT or MANY. *** If bacteria are undetected or present at very low levels, bacteria will be reported as NEGATIVE. Included in non-ionic solutes are urea, glucose, and protein. Included in ionic solutes are sodium, chloride, sulfate, phosphate, and ammonium. The refractometer method includes both ionic and non-ionic solutes. For both ionic and nonionic solutes order “Specific Gravity, Urine”.The refractometer method is routinely included in urinalysis performed at the UH and TAC Laboratories and is the method used when "SPECIFIC GRAVITY, URINE" is ordered. If a specific gravity is performed via colorimetric test strip, the following comment will appear: Only ionic solutes measured. * All UW Health Laboratories may use a screening method for specific gravity, based on a colorimetric test strips which reports only the ionic solutes. None Seen or Present calcium oxalate Present amorphous urates or phosphates Samples held at room temperature for more than 2 hours or samples refrigerated for more than 24 hours are not acceptable. Transport with coolant pack if coming from clinic location. Transport specimen to the laboratory immediately. For midstream urine collection instructions refer to Health Facts for you - Male HF #4247, Female HF # 4236 located on UConnect. Indicate whether specimen is midstream, indwelling catheter, single catheter or other method of collection. Refrigerate if transportation to lab is delayed.
