SPAN - Model RH0602I - One-Step Syphilis Rapid Test (WB/S/P)
INTRODUCTION
One Step Anti-Syphilis Test is a rapid direct binding test for the visual detection of anti-syphilis antibodies
in serum as an aid in the diagnosis of syphilis infection. Test results are read visually without any
instrument. It is based on the principle of double antigen sandwich immunoassay for determination of
syphilis antibodies in serum. Purified recombinant syphilis antigens are employed to identify
anti-Syphilis antibodies specifically. This one step test is very sensitive and only takes about 10 to 20
minutes.
SPECIMEN COLLECTION
For serum, collect blood into a container without anticoagulant. Allow the blood to clot and separate the
serum from the clot. Use the serum for testing.
If the specimen cannot be tested on the day of collection, store the serum specimen in a refrigerator or
freezer. Bring the specimens to room temperature before testing. Do not freeze and thaw the specimen
repeatedly.
TEST PROCEDURE
Strip
1.When you are ready to begin testing, open the s
SPAN - Model RA0603I - Typhoid IgG/IgM Rapid Test Cassette (Serum / Plasma)
Intended Use
The Typhoid IgG/IgM Rapid Test is a lateral flow immunoassay for the simultaneous detection and differentiation of anti-Salmonella typhi (S. typhi)G and IgM in human serum or plasma. It is intended to be used as a screening test and as an aid in the diagnosis of infection with S. typhi. Any reactive specimen with the Typhoid IgG/IgM 2.0 Rapid Test must be confirmed with alternative testing method(s).
Summary and Explanation of the Test
Typhoid fever is caused by S. typhi, a Gram-negative bacterium. World-wide an estimated 17 million cases and 600,000 associated deaths occur annually1. Patients who are infected with HIV are at significantly increased risk of clinical infection with S. typhi2. Evidence of H. pylori infection also presents an increase risk of acquiring typhoid fever. 1-5% of patients become chronic carrier harboring S. typhi in the gallbladder.
The clinical diagnosis of typhoid fever depends on the isolation of S. typhi from blood, bone marro
SPAN - Model INC-080 - Dry Blood Collection Card
The dry blood collection card contains chemically treated paper for preservation of RNA &DNA in the sample. The sample is stabilized preventing microbial or environmental degradation. It is easy to use.
Materials provided: collection card in a foil pouch with & desiccant bag.One zip-lock bag.&large shipping envelope with instruction printed on one side.
Sampling Technique:
Wash hands before and after the blood collection procedure.
Collect the blood onto the labeled filter paper, using the following protocol:
1. Cleanse infant’s heel with 70% isopropyl alcohol (use only rubbing alcohol). Note: Warming the skin-puncture site with a warm moist cloth, or a heel warming device, for 3 minutes can increase blood flow through the site.
2. Allow heel to air dry.
3. Using a lancet, or heel incision device, and wearing gloves, perform the puncture on the plantar surface of the heel. The puncture should be made to a depth of less than 2.0 mm with a sterile lancet or incision de
SPAN - Model INC-208 - Dengue IgG/IgM Rapid Tests
The assay starts with a sample applied to the sample well. A recombinant DV antigen conjugated to colloidal gold embedded in the sample pad reacts with the DV antibody present in blood, serum or plasma forming conjugate-DV antibody complex. As the mixture is allowed to migrate along the test strip, the conjugate-DV antibody complex is captured by mouse anti human IgM-µ chain (T1) or mouse anti human IgG(T2) immobilized on a membrane forming a colored test line in the test region. A negative sample does not produce a test line due to the absence of colloidal gold conjugate-DV antibody complex. The antigens used in the conjugate test are recombinant proteins that correspond to highly immunoreactive regions of DV. A colored control line in the control region appears at the end of test procedure regardless of test result. This control line is the result of colloidal gold conjugate binding to the anti-DV antibody immobilized on the membrane. The control line indicates that the colloid
SPAN - Model INC-0351 - Inf A (H1N1) Rapid Test
INTENDED USE
One Step Influenza A Test is a rapid qualitative assay that detects influenza type A (including the subtype H1N1) nucleoprotein antigen extracted from the nasal swab specimen. The device is used to aid in the diagnosis of influenza type A infection.
For in vitro diagnostic use only. For professional use only.
SUMMARY
Influenza (commonly known as ‘flu’) is a highly contagious, acute viral infection of the respiratory tract. It is a communicable disease that is easily transmitted through the coughing and sneezing of aerosolized droplets containing live virus. Influenza outbreaks occur each year during the autumn and winter months. There are three types of influenza viruses: A, B, and C. Only influenza A viruses are further classified by subtype on the basis of the two main surface glycoproteins hemagglutinin (HA) and neuraminidase (NA). Influenza A subtypes and B viruses are further classified by strains.
Humans can be infected with influenza types A, B, and
SPAN - Model INC-2 - One-step LH Ovulation Rapid Test Kit
One Step LH Urine Ovulation Test is fast and easy-to-use. It is a qualitative test that can predict when there is a LH (luteinizing hormone) surge, and in turn, when you are likely to ovulate and conceive. The tests are available in 3 different formats:
1. STRIP
2. CASSETTE
3. MIDSTREAM
The format applications range from professional to domestic usage.
WHEN TO BEGIN TESTING
First, you must determine the length of your menstrual cycle. This is the number of days from the first day of your menstrual bleeding to the day before your next bleeding begins again. Please refer to the chart below to determine when you should start testing. If your cycle is shorter than 21 days or longer than 38 days, consult your doctor. If you do not know your cycle length, you may begin the test 11 days after your first period since the average cycle length is 28 days. Perform 1 test each day over a 5 day period or until the LH surge has been detected.
URINE COLLECTION
1. Do not use first morning
SPAN - Model INC-210 - HIV1/2 Rapid Test
INTRODUCTION
One Step Anti-HIV 1+2 Test is a rapid direct binding screening test for the presence of antibodies to HIV 1 and HIV 2 viruses. The test is based on the principle of double antigen sandwich immunoassay for detection of Anti-HIV in serum and/or whole blood Purified recombinant antigens are employed to identify Anti-HIV specifically. This one step test is very sensitive and only takes about 10-15 minutes. Test results are read visually without any instrumentation.
SPECIMEN COLLECTION AND STORAGE
For serum, collect blood into a container without anticoagulant. Allow the blood to clot and separate the serum from the clot. Use the serum for testing.
If the specimen cannot be tested on the day of collection, store the serum specimen in a refrigerator or freezer. Bring the specimens to room temperature before testing. Do not freeze and thaw the specimen repeatedly.
For whole blood specimen, collect fresh blood specimen just prior to using the assay. Specimens must be fresh. Wh
SPAN - Model INC-212 - Urinalysis Reagent Strip 10P (Uncut Sheets)
PRINCIPLE AND EXPECTED VALUES
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.
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.3 Glucose
concentrations as low as 100 mg/dL, read at either 10 or 30 seconds, may be
considered abnormal if results are consistent. At 10 seconds, results should be
interpreted qualitatively. For semi-quantitative results, read at 30 seconds only.
Bilirubin: This test is based on azo-coupling reaction of b
