The device description and intended use clearly state that results are obtained by visual comparison with a color chart, and no instrumentation or software is mentioned.
No
The device is for diagnostic purposes, specifically for detecting various substances in urine, which provides information for diagnosis rather than directly treating a condition.
Yes
The device detects specific analytes in urine (e.g., glucose, bilirubin, protein) which provides information regarding the status of various bodily functions (carbohydrate metabolism, kidney function, liver function), thus aiding in the identification or monitoring of medical conditions.
No
The device description explicitly states it is a "Plastic strips with reagent pads" and describes a physical product that reacts with urine and provides a visible color reaction. It is a hardware-based diagnostic test.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is for the "detection of glucose, bilirubin, ketone, specific gravity, blood, pH, protein, urobilinogen, nitrite and leukocytes in urine." This involves testing a biological sample (urine) outside of the body to gain information about a person's health status.
- Device Description: The device is a "plastic strip with reagent pads which provide a color change when exposed to urine." This describes a test that is performed in vitro (in glass or outside the body) using chemical reagents.
- Professional Use: While it mentions professional use, the core function is the analysis of a biological sample in vitro.
- Comparison to Predicate: The comparison to the Bayer MultiStix® 10 SG, which is a known IVD, further supports its classification as an IVD.
The definition of an IVD generally includes devices intended for use in the collection, preparation, and examination of specimens taken from the human body for the purpose of providing information for the diagnosis, treatment, or prevention of disease. The AimStick® Urine Reagent Strips clearly fit this description.

Device Name: | AimStick® Urine Reagent Strips |
---|---|
Common Name: | Urinalysis Reagent Strips |
Device Description: | Plastic strips with reagent pads which provide a color change when |
exposed to urine. | |
Medical Specialty: | Clinical Chemistry |
Intended Use: | The AimStick® Urine Reagent Strips are intended for detection of |
glucose, bilirubin, ketone, specific gravity, blood, pH, protein, | |
urobilinogen, nitrite and leukocytes in urine. | |
Product Description: | The AimStick® Urine Reagent Strips are plastic strips to which |
Glucose, Bilirubin, Ketone, Specific Gravity, Blood, pH, Protein, | |
Urobilinogen, Nitrite and Leukocyte reagent pads are affixed. The | |
reagent pads react with the urine and provide a visible color reaction. | |
The product is packaged with a drying agent in a plastic bottle. Each | |
strip is stable and ready to use upon removal from the bottle. The | |
entire reagent strip is disposable. The directions must be followed | |
exactly. Results are obtained by direct comparison of the test strip | |
with the color blocks printed on the bottle label. Laboratory | |
instrumentation is not required. | |
Tests Principles: | |
Glucose: | This test is based upon the enzymatic glucose oxidase/peroxidase |
(GOD/POD) method. Glucose oxidase catalyzes the formation of gluconic | |
acid and hydrogen peroxide from the oxidation of glucose. A second | |
enzyme, peroxidase, catalyzes the reaction of hydrogen peroxidase with a | |
potassium iodide chromogen to oxidize the chromogen to colors ranging | |
from green to blue. | |
Bilirubin: | This test is based upon the coupling of bilirubin with diazotized |
dichloroaniline in a strongly acid medium. The colors produced on the | |
reagent pad ranges through various shades of beige or tan. | |
Ketone: | This test is based upon the reaction between acetoacetate and sodium |
nitroprusside in an alkaline medium. A positive result is indicated by a color | |
change on the reagent pad from beige to violet. | |
Specific Gravity: | This test is based upon the release of protons in the presence of cations. The |
reaction produces hydrogenous ionogen, which reacts with pH indicator. | |
Colors produced range from deep blue-green through yellow-green. | |
Blood: | This test is based upon hemoglobin reacting as peroxidase. Intact |
erythrocytes hemolyze on the test pad and the hemoglobin released produces | |
a green dot. Scattered green dots on the yellow test pad are indicative of | |
intact erythrocytes. A uniform green color is indicative of released | |
hemoglobin, myoglobin, or hemolyzed erythrocytes. The colors produced | |
range from orange through green. | |
pH: | The test is based upon the well known method of pH indicators methyl red |
and bromthymol blue. The colors range from orange through yellow and | |
green to blue. | |
Protein: | This is based upon the protein-error-of-indicator principle. Anion in the |
specific pH indicator attracted by cation on protein molecules makes the | |
indicator further ionized, which changes its color. A positive reaction is | |
indicated by a color change from yellow to light green and to darker greens. |

- Urobilinogen: This test is based on the Ehrlich reaction in which p-diethylamino This "is "is "based" unction with a color enhancer reacts with urobilinogen in a Strongly acid medium. A positive reaction is indicated by a pink-reddish color.
- This test is based upon the conversion of Nitrate to Nitrite. The Nitrite in the Nitrite: rine and aromatic amino sulphanilamide are diazotized to form a diazonium urine aromatio The diazonium compound reacting with tetrahydro benzo(h) quinolin 3-phenol causes the color change. A positive reaction is indicated by a light pink to pink color.
- This test is based upon the reaction of esterases, present in granulocytic Leukocytes: leukocytes, which catalyzc the hydrolysis of an indoxylcarbonic acid ester to indoxyl. A positive reaction is indicated by a light purple to dark purple color.
Characteristics of the AimStick® Urine Reagent Strips are compared with the Bayer MultiStix® 10SG system in the following table:

between acetoacetate and | ||
sodium nitroprusside in an | ||
alkaline medium. A positive | ||
result is indicated by a color | ||
change on the reagent pad | ||
from beige to violet. | Based on the development of | |
colors ranging from buff-pink | ||
for a negative reading, to | ||
purple when acetoacetic acid | ||
reacts with nitroprusside. | ||
Specific Gravity | ||
Methodology | Based upon the release of | |
protons in the presence of | ||
cations. The reaction | ||
produces hydrogenous | ||
ionogen, which reacts with | ||
pH indicator. Colors | ||
produced range from deep | ||
blue-green through yellow- | ||

polyelectrolytes in relation | ||
with ionic concentration. In | ||
the presence of an indicator, | ||
colors range from deep blue- | ||
green through green and | ||
yellow-green. | ||
Blood Methodology | Based upon hemoglobin | |
reacting as peroxidase. Intact | ||
erythrocytes hemolyze on the | ||
test pad and the hemoglobin | ||
released produces a green | ||
dot. Scattered green dots on | ||
the yellow test pad are | ||
indicative of intact | ||
erythrocytes. A uniform | ||
green color is indicative of | ||
released hemoglobin, | ||
myoglobin, or hemolyzed | ||
erythrocytes. The colors | ||
produced range from orange | ||
through green. | Based on the peroxidase-like | |
activity of hemoglobin, which | ||
catalyzes the reaction of | ||
diisopropylbenzene | ||
dihydroperoxide and 3,3',5,5' | ||
tetramethylbenzidine. The | ||
resulting color ranges from | ||
orange through green. | ||

reaction in which p- | ||
diethylaminobenzaldehyde in | ||

enhancer reacts with | ||
urobilinogen in a strongly | ||
acidic medium to produce a | ||
pink-red color. | ||
Nitrite Methodology | Based upon the conversion of | |
Nitrate to Nitrite. The Nitrite | ||
in the urine and aromatic | ||
amino sulphanilamide are | ||
diazotized to form a | ||
diazonium compound. The | ||
diazonium compound | ||
