Final answer:
High specific gravity range in urine indicates fluid overload. White blood cell count can indicate infection. A fever is a body temperature above 100.4°F (38°C)
Step-by-step explanation:
High specific gravity is a measure of the quantity of solutes per unit volume of urine. A high specific gravity range in urine indicates fluid overload. Urine will always have a specific gravity greater than pure water due to the presence of solutes. Laboratories can now measure urine osmolarity directly, which is a more accurate indicator of urinary solutes than specific gravity.
White blood cell count in infection: From an infectious disease perspective, the number of white blood cells and the relative percentages of different types of cells may indicate whether a person has an infection or not. A raised white cell count (neutrophilia) suggests infection.
Temperature range for a fever: An elevated temperature may be an indication of an infection or other conditions such as cancerous tumor or decline in blood flow. A fever is generally considered to be a body temperature above 100.4°F (38°C). Dark blue and red areas in an infrared thermograph indicate temperature abnormalities.
