Reference ranges for urine tests are described below: Measurement Lower limit Upper limit Unit Urinary specific gravity: 1.003 [1] [2] 1.030 [1] [2] g/mL Urobilinogen:
This enables normal peristalsis instead of abnormal contraction and retrograde movement of bowel contents. [16] Researchers demonstrated that patients who had positive results with biofeedback had evidence of improved autonomic innervation of the colon, increased colonic transit time, and had increased quality of life scores.

Lactulose is a carbohydrate that is not absorbed by humans. Lactulose is well known to measure oro-cecal transit time. [11] [1] [4] The mean oro-cecal transit time in normal healthy individuals is 70 to 90 minutes. [12] [13] [8] By 90 minutes, at least 50% of individuals would have delivered the lactulose dose to the colon. Approximately 90 to ...
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

The time taken for food to transit through the gastrointestinal tract varies on multiple factors, including age, ethnicity, and gender. [ 28 ] [ 29 ] Several techniques have been used to measure transit time, including radiography following a barium -labeled meal, breath hydrogen analysis, scintigraphic analysis following a radiolabeled meal ...
A stool test is a medical diagnostic technique that involves the collection and analysis of fecal matter. Microbial analysis (culturing), microscopy and chemical ...
The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/(1.73 m 2) in men and 90–120 (mL/min)/(1.73 m 2) in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m 2 ) until 2 years of age in both sexes, and then it progressively decreases.
