A heat map is a top-view map of an area with visual indicators showing a specific set of objects on the map based on certain comp criteria, which then translates into the objects on the map giving different visual cues depending on the difference of scale of the predetermined criteria to give information about the said objects and their locations.
For a more extensive test, your doctor might ask you to collect your urine over a 24-hour period. Normal values of protein in urine are typically between 0 and 20 mg/dL. For the 24-hour collection, anything below 80 mg/dL is considered normal. Again, remember that the range might vary, depending upon the laboratory used.
It is claimed that spot protein /creatinine ratio corresponds to 24 hours urine protein excretion. For example if the spot urine protein is 300 mg / dl and spot urine creatinine is 150 mg / dl, the ratio will be 300 / 150 = 2 which means 24 hours urine protein excretion is 2 gram.
