INSTRUCTION MANUAL

INSTRUCTIONS FOR USE

PLEASE READ ALL THE INFORMATION IN THIS INSERT BEFORE PERFORMING THE TEST.

This package insert applies to any combination of the multi-drug tests. Therefore, some information may not be relevant to your test. You can identify which drugs and associated cutoffs are included in your test from the box labels and prints on the test device.

INTENDED USE

RAPID DRUG TEST CUP is an immunoassay for the qualitative determination of single or multiple drugs in human urine at the cutoff concentrations of table below.

RAPID DRUG TEST CUP offers any combinations from 1 to 16 drugs but only one cutoff concentration under same drug condition will be included per device .
The test is CLIA Waived and is intended for over-the-counter (OTC) use.

For in vitro diagnostic use only.

The test provides only preliminary results. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result. To obtain a confirmed analytical result, a more specific alternate chemical method is needed. GC/MS or LC/MS is the recommended confirmatory method.

WARNINGS AND PRECAUTIONS

• For external use only. Do not swallow.
• Discard after first use. The test cannot be reused.
• Do not use the test device beyond expiry date.
• Do not use the test device if the pouch is punctured or not well sealed.
• Keep out of the reach of children.
• Read the test result at 5 minutes. Do not read the result after 60 minutes.
• The test is only the first step of the two-step process to provide consumers with information about the presence or absence of the above stated drugs in a urine sample. If you get a ‘preliminary positive’ test result when you use this product, the second step is to mail a portion of the urine sample in the provided materials to the laboratory for confirmation testing.
• By itself, this test will not confirm if someone used a drug of abuse. These types of tests may incorrectly detect the presence of a drug of abuse when the person has consumed certain foods, medicines, diet plan drugs, or nutritional supplements. These are just some examples of the types of things that can cause a false result and there may be others as well. In order to show if someone used a drug of abuse, you will need to send the urine sample to a laboratory to have a second test, called a confirmation test, performed. The cost of the additional testing is not included in the purchase price of this screening test kit.

SPECIMEN COLLECTION AND STORAGE

WHEN TO COLLECT URINE FOR THE TEST?

Urine collected at any time of the day may be used. You may collect urine samples after the minimum detection time when you suspect you’ve taken drugs.

HOW TO COLLECT URINE?

Remove the test cup from the foil pouch by tearing at the notch and use it as soon as possible. Open the cap of the test cup and void directly into the test cup to reach the minimum urine level. Wipe off any splashes or spills that may be on the outside of the cup.

IMPORTANT: The urine sample in the test cup should be enough to reach the Minimum Urine Level on the cup label.

HOW TO DO THE TEST?

Test must be performed at room temperature (59℉- 86℉ / 15°C – 30°C).

1. After the urine has been collected, re-cap the test cup and place the test cup on a flat surface.
2. Start the timer. Peel the label from right to left.
3. For the adulteration strip(s) if equipped: Read results immediately, or at 30 seconds, or at 45 seconds and compare each adulterant pad to verify pad color is within acceptable range according to the adulteration color comparison chart. If the results indicate adulteration, do not read the drug test results. Instruct the donor to provide urine specimen again with another new test cup.
4. For the drug tests: Read the drug test results at 5 minutes. Do not read the result after 60 minutes.

READING THE RESULTS

ADULTERATION CONTROL:

Semi-quantitative results are obtained by visually comparing the color of each pad with the corresponding color blocks on the enclosed color chart.

DRUG-OF-ABUSE TEST:

Preliminary positive (+)
A color band is visible in each control region (C). If no color band appears in the appropriate drug test region (T), a preliminary positive result is indicated for the corresponding drug of that specific test region.

Negative (-)

If a color band is visible in each control region (C) and the appropriate drug test region (T), it indicates that the concentration of the corresponding drug of that specific test region is absent or below the detection limit of the test.

Invalid
If a color band is not visible in the control region (C), the test is invalid. Another test should be run to re-evaluate the specimen. If test still fails, please contact the distributor or the store, where you bought the product, with the lot number.

Note: There is no meaning attributed to line color intensity or width. Any visible line is considered to be a line.

A preliminary positive test result does not always mean that a person took illegal drugs. A negative test result does not always mean that a person did not take illegal drugs. There could be a number of factors that affect the reliability of drug tests.

IMPORTANT:

The result you obtained is called preliminary for a reason. The sample must be tested by laboratory in order to determine if a drug of abuse is actually present. Send any sample which does not give a negative result to a laboratory for further testing.

What Is A False Positive Test?

The definition of a false positive test would be an instance where a substance is identified incorrectly by RAPID DRUG TEST CUP. The most common causes of a false positive test are cross reactants. Certain foods and medicines, diet plan drugs and nutritional supplements may cause a false positive test result with this product.

What Is A False Negative Test?

The definition of a false negative test is that the initial drug is present but isn’t detected by RAPID DRUG TEST CUP. If the sample is diluted or adulterated that may cause false negative result.
If you get a negative test result but you still suspect someone is taking drugs you should test again at another time, or test for different drugs.

ADULTERATION CONTROL

Expected Results

Creatinine (CRE): Daily creatinine excretion, related to muscle mass of the human body, is usually constant. The DOT guideline states that urine specimens with creatinine levels of less than 20 mg/dl are indications of adulteration. Although these ranges are affected by age, sex, diet, muscle mass and local population distribution2, sample with creatinine level of lower than 20 mg/dl should be considered adulterated.
Glutaraldehyde (GLU): Glutaraldehyde is not a natural component of human urine and it should not be present in normal urine. The presence of glutaraldehyde in the urine sample indicates the possibility of adulteration. However, false positive may result when ketone bodies are presence in urine. Ketone bodies may appear in urine when a person is in ketoacidosis, starvation or other metabolic abnormalities.

Nitrite (NIT): Although nitrite is not a normal component of urine, nitrite levels of up to 3.6 mg/dl may be found in some urine specimens due to urinary tract infections, bacterial contamination or improper storage. In this adulteration control, nitrite level above 7.5 mg/dl is considered abnormal.

pH: Normal urine pH ranges from 4.5 to 8.0. Values below pH 4.0 or above pH 9.0 are indicative of adulteration.

Specific Gravity (S.G.): Random urine may vary in specific gravity from 1.003 – 1.030. Normal adults with normal diets and normal fluid intake will have an average urine specific gravity of 1.016 – 1.022. Elevated urine specific gravity value may be obtained in the presence of moderate quantities of protein. DOT guidelines state that a urine specimen with specific gravity level of less than 1.003 is an indication of adulteration. Specific gravity and creatinine values should be considered together to provide a better picture of whether the sample is adulterated.

Oxidants (OXI): The presence of Bleach and other oxidizing reagents in the urine is indicative of adulteration since oxidizing reagents are not normal constituents of urine. Other oxidizing reagents include Hydrogen Peroxide, Ferricyanide, Persulfate, Pyridinium Chlorochromate…etc.

Pyridinium Chlorochromate (PCC): The presence of any chromate in urine is indicative of adulteration as chromate is not a normal constituent of urine.

MAILING A URINE SAMPLE TO THE LABORATORY FOR CONFIDENTIAL CONFIRMATION TESTING

Only urine that gave preliminary positive result(s) should be sent to a lab for confirmation testing.

1. Open the Labeled Vial and carefully pour the urine sample from the test cup into the Labeled Vial. Fill the vial to about two-thirds (2/3) full and tightly close the cap. Make sure that the number on the Labeled Vial matches your Personal Identification Number.
2. Check the label identifying the drug that was a preliminary positive result.
3. Place the Labeled Vial in the plastic bag and seal the plastic bag.
4. Place the sealed plastic bag in the mailing box. Close the mailing box and secure it with packing tape. The mailing address is already on the mailing box.
5. Place the mailing box and pay the postage at any US Postal Service Office.

IMPORTANT:
You may call or send an email for the confirmed test results along with the Personal Identification Number. The phone number and email address are already on the mailing box. Please do not forget to mark down the phone number and email address.

TEST LIMITATIONS

1. This test has been developed for testing urine samples only. No other fluids have been evaluated. DO NOT use this device to test specimen other than urine.
2. Technical or procedural errors, as well as interfering substances in the urine specimen may cause incorrect results.
3. Contaminated or adulterated urine samples may produce incorrect results. Strong oxidizing agents such as bleach (hypochlorite) can oxidize drug analyte. If a sample is suspected, repeat the test with another urine sample.
4. This test is a qualitative screening assay. It is not designed to determine the quantitative concentration of drugs or the level of intoxication.
5. A negative result may not indicate drug-free urine. Negative results can be obtained when drug is present but below the cut-off level of the test.
6. You can’t retrieve your confirmed results without knowing your PIN (Personal Identification Number).

PERFORMANCE CHARACTERISTICS

A. Accuracy

1600 (eighty of each drug) clinical urine specimens were analyzed by LC-MS/MS and by each corresponding drug of abuse Test. Each test was read by three viewers. Samples were divided by concentration into five categories: drug-free, less than half the cutoff, near cutoff negative, near cutoff positive, and high positive. Results were as follows:

B. Precision and Sensitivity

To investigate the precision and sensitivity,  each drug samples were analyzed at the following concentrations: +100% cutoff, +75% cutoff, +50% cutoff, +25% cutoff, cutoff, -25% cutoff, -50% cutoff,- 75% cut off and -100% cutoff. All concentrations were confirmed with LC-MS/MS. The study was performed 2 runs /day and lasted 25 days using three different lots of the corresponding drug of abuse test. Totally 3 operators participated in the study of the corresponding drug of abuse test. Each of the 3 operators tests 2 aliquots at each concentration for each lot per day (2 runs /day), for a total of 50 determinations per concentration per lot of the corresponding drug of abuse test.

C. Specificity and cross reactivity

The following table lists the concentration of compounds (ng/mL) above which the RAPID DRUG TEST CUP identified positive results.

D. Interfering substances

A study was conducted to determine the interference of the test with the following compounds. The following compounds showed no interference when tested with the RAPID DRUG TEST CUP at a concentration up to 100 μg/mL.

F. Effect of Urinary pH

The pH of an aliquot negative urine pool is adjusted to a pH range of 4 to 9 in 1 pH unit increments and spiked with each drug at 25% below and 25% above cutoff levels. Each sample was tested by the test device. The result demonstrates that varying range of PH do not interfere with the performance of the test.

QUESTIONS AND ANSWERS

1. What does the RAPID DRUG TEST CUP do?
These tests indicate if one or more prescription or illegal drugs are present in urine. These tests detect the presence of drugs such as amphetamine, secobarbital, buprenorphine, oxazepam, benzoylecgonine, EDDP, MDMA, methamphetamine, morphine, methadone, oxycodone, phencyclidine, propoxyphene, nortriptyline, marijuana and 6-Monoacetylmorphine.
The testing is done in two steps. First, you do a quick at-home test. Second, if the test suggests that drugs may be present, you need to send the sample to a laboratory for confirmation testing.

2. What is “cut-off level”?
The cut-off level is the specified concentration of a drug in a urine sample. Above that concentration the test result is positive, and below is negative.

3. What are drugs of abuse?
Drugs of abuse are illegal or prescription drugs (for example, Oxycodone or Valium) that are taken for a non-medical purpose, including taking the medication for longer than your doctor prescribed it for or for a purpose other than what the doctor prescribed it for.

4. What are the Common Street Names for the Drugs to be detected?

5. How accurate is the test?

The tests are sensitive and accurate. These tests, however, are not as accurate as confirmatory tests. In some cases, certain foods and drugs may cause false positives as well as false negatives for those who use drug- testing kits.

6. If the test results are negative, can the conclusion be that the person is free of drugs?

This means that if the sample was collected properly and if the test was performed according to direction, none of the drug were present at concentrations above the cutoff.

7. Does a preliminary positive screen test mean that drugs of abuse have been found?

This means that the test has reacted with something in the sample and the sample must be sent to the lab for a more accurate test.

8. What should I do, if the lab test confirms a positive result?

If you have received a confirmed positive result, please consult with counselor for a proper course of action. It is important that you remain calm and do not react in a negative way to the situation. If you do not believe the test result, please consult with your physician. They will have your background medical history and provide you with detailed information on both the test and the meaning of the result.
