Although the primary purpose of these forums is to help Vudu customers with questions and/or problems with their Vudu service, there are also off-topic areas available within the Vudu Forums for users to chat with like-minded people, subject to the limitations below. on the subject of Vudu and Vudu -related issues (home theater, entertainment, etc). Here, Vudu customers may post information, questions, ideas, etc. False positive reactions can also be caused by vegetable peroxidase.The Vudu Forums are designed to help viewers get the most out of their Vudu experience. Bacterially contaminated urine specimens may contain sufficient peroxidase activity to produce a false positive reaction. Urine should be tested shortly after collection because red cell lysis may occur as the sample ages, if the pH is alkaline, or if the specific gravity is 1.010 or less. Any situation that causes red cell hemolysis will give a positive dipstick and negative microscopic result. Many conditions can lead to discrepant dipstick and microscopic findings. No etiology can be determined in approximately 45% of cases of microscopic hematuria.Ī positive dipstick test for blood does not tell whether the reaction is due to red cells, red cell casts, hemoglobin casts, or myoglobin. Anticoagulant therapy and chemotherapy may also cause hematuria. Transient hematuria can result from menstruation, viral illnesses, strenuous exercise, and mild trauma. The most common disorders include cancer, kidney stones, renal disease, urinary tract infection, and benign prostatic hyperplasia. Hematuria can be due to lesions within the GU tract involving the kidneys, ureters, bladder, prostate, or urethra. Gross hematuria occurs when more than 1 million red cells are excreted per minute. When 3000 to 4000 red cells are excreted per minute, 2 to 3 red cells will be seen per high power field, indicating microscopic hematuria. In healthy individuals, fewer than 1000 red cells are excreted in the urine per minute. Certain medications (aspirin or penicillin) Recent infection (particularly of the kidneys in children) Sex (women with urinary tract infections, men with kidney stones) There are some risk factors that can put you at risk for hematuria such as:

Your healthcare professional will investigate further to try to determine the source and underlying cause of the blood. Blood in the urine, called hematuria, is not a normal finding, but it is not uncommon and not necessarily a cause for alarm. Normal urine doesn’t contain red blood cells, except females’ urine during menstruation.
Occult blood is blood that cannot be seen without a microscope.
This concentration corresponds to 5 to 21 RBCs/uL or 1 to 4 RBCs/hpf of concentrated urine sediment. The sensitivity of dipsticks for hemoglobin is 0.015 to 0.062 mg/dL. Therefore, trace to 1+ reading may be obtained on urine from as many as 3% of healthy individuals. Dipstick sensitivity extends into the reference range. This range corresponds to a concentration of 3 to 20 RBCs/uL of urine. The reference range for RBCs in normal urine is 0-3 RBC/hpf in males and 0-12 RBCs/hpf in females when concentrated urine sediment is examined. If intact red cells do not lyse, they may produce speckles on the pad. Tetramethylbenzidine is oxidized, producing a color change from orange to green-blue.

Red cells are lysed on contact with the strip, allowing free hemoglobin to catalyze the liberation of oxygen from organic peroxide. The dipstick test for blood is based on the peroxidase-like activity of hemoglobin. Typically, this is done by dipping a strip into the urine sample, and chemical reactions change the color of the pads.

Urinalysis refers to a series of tests that can be run to assess the chemical quality of urine.
