No
The device description explicitly states that results are obtained by direct visual comparison with color blocks, and laboratory instrumentation is not required. There is no mention of any computational analysis or algorithms.
No
The device is a diagnostic tool used to detect analytes in urine for screening and assisting diagnosis; it does not provide therapy or treatment.
Yes
The intended use explicitly states that the strips are "intended for use in screening at-risk patients to assist diagnosis" in various areas and that "The results can be used along with other diagnostic information to rule out certain disease states". This directly aligns with the definition of a diagnostic device.
No
The device is a physical reagent strip that reacts with urine and is read visually. It is a hardware device, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The device is intended for the qualitative and semi-quantitative detection of analytes in urine. This involves testing a sample taken from the human body (in vitro) to provide information for diagnostic purposes (assisting diagnosis in various areas like kidney function, urinary tract infections, etc.).
- Sample Type: It uses urine, which is a biological specimen.
- Purpose: The results are used to assist diagnosis, rule out certain disease states, and determine if further analysis is needed. This directly aligns with the definition of an IVD.
- Device Description: It describes reagent pads that react with urine to produce a visible color reaction, which is a common method for in vitro diagnostic tests.
- Clinical Studies: Performance studies were conducted to evaluate clinical accuracy, comparing the device to legally marketed IVD predicate devices.
All these points strongly indicate that the ACON Urinalysis Reagent Strips (Urine) fall under the category of In Vitro Diagnostic devices.

The results can be used along with other diagnostic information to rule out certain disease states and to determine if microscopic analysis is needed. The test is to be read visually. It is intended for professional use only.
Tests Principles:
Glucose: This test is based on the enzymatic reaction that occurs between glucose oxidase, peroxidase and chromogen. Glucose if first oxidized to produce gluconic acid and hydrogen peroxide in the presence of glucose oxidase. The hydrogen peroxide reacts with potassium iodide chromogen in the presence of peroxidase. The extent to which the chromogen is oxidized determines the color which is produced, ranging from green to brown. Low amounts of glucose are normally excreted in urine. Glucose concentrations as low as 100 mg/dL, read at either 10 or 30 seconds, may be considered abnormal if results are consistent.
Bilirubin: This test is based on azo-coupling reaction of bilirubin with diazotized dichloroaniline in a strongly acidic medium. Varying bilirubin levels will produce a pinkish-tan color proportional to its concentration in urine. In normal urine, no bilirubin is detectable by even the most sensitive methods. Even trace amounts of bilirubin require further investigation. Atypical results (colors different from the negative or positive color blocks shown on the color chart) may indicate that bilirubin-derived bile pigments are present in the urine specimen, and are possibly masking the bilirubin reaction.
3
Ketone: This test is based on ketones reacting with nitroprusside and acetoacetic acid to produce a color change ranging from light pink for negative results to a darker pink or purple color for positive results. Ketones are normally not present in urine. Detectable ketone levels may occur in urine during physiological stress conditions such as fasting, pregnancy and frequent strenuous exercise. In starvation diets, or in other abnormal carbohydrate metabolism situations, ketones appear in the urine in excessively high concentration before serum ketones are elevated.
Specific Gravity: This test is based on the apparent pKa change of certain pretreated polyelectrolytes in relation to ionic concentration. In the presence of an indicator, colors range from deep blue-green in urine of low ionic concentration to green and yellow-green in urine of increasing ionic concentration. Randomly collected urine may vary in specific gravity from 1.003-1.035. Twenty-four hour urine from healthy adults with normal diets and fluid intake will have a specific gravity of 1.016-1.022. In cases of severe renal damage, the specific gravity is fixed at 1.010, the value of the glomerular filtrate.
Blood: This test is based on the peroxidase-like activity of hemoglobin which catalyzes the reaction of cumene-hydropcroxide and 3,3',5,5'-tetramethylbenzidine. The resulting color ranges from orange to green to dark blue. Any green spots or green color development on the reagent area within 60 seconds is significant and the vurine specimen should be examined further. Blood is often, but not invariably, found in the urine of menstruating females.
pH: This test is based on a double indicator system which gives a broad range of colors covering the entire urinary pH range. Colors range from orange to yellow and green to blue. The expected range for normal urine specimens from newborns is pH & For to expected range for other normal urine specimens is pH 4.5-8, with an average result of pH 6.
Protein: This reaction is based on the phenomenon known as the "protein error" of pH indicators where an indicator that is highly buffered will change color in the resence of proteins (anions) as the indicator releases hydrogen ions to the protein. At a prosence pH, the development of any green color is due to the presence of protein. Colors range from yellow to yellow-green for negative results and green to green-blue for positive results. 1-14 mg/dL of protein may be excreted by a normal kidney. A color matching any block greater than trace indicates significant proteinuria.
Urobilinogen: This test is based on a modified Ehrlich reaction between pdiethylaminobenzaldehyde and urobilinogen acid in strongly acidic medium to produce
4
a pink color. Urobilinogen is one of the major compounds produced in heme this test is 0.2-1.0 mg/dL (3.5-17 umol/L). A result of 2.0 mg/dL (35 umol/L) may be of clinical significance, and the patient specimen should be further evaluated.
Nitrite: This test depends upon the conversion of nitrate to nitrite by the action of Gram negative bacteria in the urine. In an acidic medium, nitrite in the urine reacts with p-arsanilic acid to form a diazonium compound. The diazonium compound in turn couples with 1 N-(1-naphthyl)-ethylenediamine to produce a pink color. Nitrite is not detectable in normal urine. The nitrite area will be positive in some cases of infection, depending on how long the urine specimens were retained in the bladder prior to collection. Retrieval of positive cases with the nitrite test ranges from as low as 40% in cases where little bladder incubation occurred, to as high as approximately 80% in cases where bladder incubation took place for at least 4 hours.
Leukocytes: This test reveals the presence of granulocyte esterases. The esterases cleave a derivatized pyrazole amino acid ester to liberate derivatized hydroxy pyrazole. This pyrazole then reacts with a diazonium salt to produce a beige-pink to purple color. Normal urine specimens generally yield negative results. Trace results may be of questionable clinical significance. When trace results occur, it is recommended to retest using a fresh specimen from the same patient. Repeated trace and positive results are of clinical significance.
Ascorbic acid: This test involves decolorization of Tillmann's reagent. The presence of ascorbic acid causes the color of the test field to change from blue-green to orange.
Substantial Equivalence:
The ACON Urinalysis Reagent Strips are substantially equivalent to the Bayer Multistix 10 SG Reagent Strips for Urinalysis (K905396) and the Quidel QuickVue UrinChek 10+SG (K861255).
