Home \ Products \ Urinalysis \ Convergys® Urine Matrix Overview Product Brochure Main FeaturesDetailed Technical Specifications Ascorbic Acid also known as Vitamin C can produce false negative results at high concentrations in urine samples. Convergys® Urine Matrix test strips are protected against interference of ascorbic acid in common concentrations now. Convergys® Urine Matrix test strips for in vitro diagnostic provide useful screening information regarding the status of carbohydrate metabolism, kidney, liver function, acid-base balance and urinary tract infections. The method of screening patients for a wide range of diseases with urine test strips is a worldwide established method. Only the pathological indications of test parameters need further diagnostic intervention. Convergent Technologies offers a range of easy to use urine test strips for screening several indications. It is also very helpful for further follow-up and monitoring of risk patients. Convergys® Urine Matrix test strips can be used to identify patients possibly with a urinary tract or kidney infection, kidney failure, diabetes mellitus, high blood pressure (hypertension) or some other diseases.
All Convergys® Urine Matrix strips tests can be performed within 1-2 minutes. With Convergys® Urine Matrix test strips you can screen the patients for a wide range of developing diseases. Convergys® Urine Matrix test strips are for in vitro diagnostic use. The visual method makes it easy to get results with Convergys® Urine Matrix test strips.

Red Blood Cells and Hemoglobin White Blood Cell (WBC) Sum-up Dipstick (renal colic) Urine Sediment: A quick, direct test for urine is to centrifuge a tube of fresh urine and put a smear of the sediment on a glass slide and inspect under microscope for distinctive shaped bodies, bacteria and other micro-organisms. Any bacteria found is abnormal and means infection and may often be diagnosed by distinctive shape or staining. Also special urine sediment bodies tell much about the course of kidney diseases. It is an absolutely essential part of all urine tests.To read on, click at your leisure for fun reading.Human and animal diabetics both use ketostix or ketodiastix. These are reagent indicator strips that test urine for only ketone (ketostix) or for both ketones and glucose (ketodiastix).
These links show examples of Ketostix[1] and Ketodiastix[2]. These stix are available at any brick-and-mortar or Internet pharmacy that sells human diabetic supplies. Stix do expire, so check the unopened expiration date when you buy them and record the date you open them. Keep the bottle tightly closed when not in use; prolonged exposure to air can produce false negative urine ketone test results[3]. If the foil-wrapped Ketostix, rather than the ones in vials are purchased, you may find it less wasteful. After the bottle is opened, the remaining unused strips have only a 6 months' life. By using the foil-wrapped ones, you can extend the "life" of your purchase. The singly-wrapped ones can have a unopened expiration date of up to two years. You are then only using what you need when you need it, having the rest still sealed and potent until the indicated expiration date[4]. You should test your pet's urine for ketones for the reasons discussed at ketones. You may test your pet's urine for glucose because (1) you've been instructed to do so by the vet as a method of gauging regulation, (2) your pet is undiagnosed and you want to determine whether there is hyperglycemia, or (3) your cat is in remission and you want to determine whether there is hyperglycemia.
Some reasons for preferring testing glucose levels by using blood over urine testing is that the urine used in testing may have been in the bladder for hours. Because of this, it may not be a reliable indicator of what systemic glucose levels are at the time of testing[5]. What's seen when testing urine for glucose is an average of what the level of glucose has been over a period of about 5-8 hours (the time period from last urination)[6]. Urine testing[7] also makes it more difficult to determine whether any hyperglycemia noted is the result of a Somogyi rebound pattern or a true need for an increase in insulin dosage. Urine only tests positive for glucose when the renal threshold has been exceeded for a length of time[8]. There also must be some degree of glycosuria (glucose in urine) present in order for a urine test to detect development of hypoglycemia[9].The stix bottle has instructions and color charts to show you how the color on the stix will change given the level of ketones/glucose in the urine over 15 (ketones) or 30 (glucose) seconds.
Be sure to read the colors at those time intervals because the colors will continue to darken and a later reading will be an incorrect result. Timing with a clock or watch second hand instead of counting is said to be more accurate[10]. In a diabetic, any urinary ketones above trace, or any increase in urinary ketone level, or trace urinary ketones plus some of the symptoms above, are cause to call an emergency vet immediately, at any hour of the day. When testing urine for ketones, the sample needs to be as fresh as possible. Ketones evaporate quickly, so there's a chance of getting a false negative test result if you're testing older urine[11]. At low levels, ketones can be detected in the urine (ketonuria) before they are found in the blood (ketonemia/ketonaemia)[12]. See Urine testing stix, Reading Results for examples of ketodiastix and ketostix color charts.

If your pet is taking any type of vitamin supplements, it should be noted on his or her medical records. Knowing that he/she is using them means being able to factor them into interpretations of test results.

Positive-lack of fluids can concentrate ketones Negative-ketones can evaporate rapidly. How to catch urine. Some people place the stix under their pet's stream when s/he is urinating. Others catch urine in a dedicated spoon, ladle, or other collection device and dip the stix into the urine.
