INTENDED USE The Finecare™ 2019-nCoV lgM/lgG Test is a fluorescence immunoassay used along with Finecare™ FIA Meters for qualitative detection of IgG and IgM antibodies of novel coronaviruses (2019-nCoV) in human whole blood, serum and plasma specimen. Clinically, the test is to be used as an aid in the diagnosis of coronavirus infection disease (COVID-19), which is caused by 2019-nCoV. The test provides preliminary test results. Negative results cannot exclude the possibility of 2019-nCoV infection and they cannot be used as the sole basis for treatment or other management decision. STORAGE AND STABILITY 1. Store at 4-30°C in the sealed pouch up to the expiration date printed on the package. Do not freeze. 2. The test device should be used within 1 hour after taking out from the foil envelope. 3. Keep away from sunlight, moisture and heat. 4. Kit contents are stable until the expiration date printed on the outer box.

The OnSite Troponin I Combo Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection of cardiac Troponin I (cTnI) in human serum, plasma or whole blood at a level equal to or higher than 1 ng/mL. It can be performed within 15 minutes by minimally skilled personnel, and without the use of laboratory equipment. The OnSite Troponin I Combo Rapid Test is intended to be used by healthcare professionals as an aid in the diagnosis of acute myocardial infarction (AMI). Any use or interpretation of this preliminary test result must also rely on patient’s symptoms and the professional judgment of a physician. A more precise test method such as an instrument method must be used to confirm the test result obtained by this device. Normally the level of cTnI in the blood is very low. cTnI is released into the blood stream in forms of free cTnI and cTnI-C-T complex at 4-6 hours after myocardial cell damage. The elevated level of cTnI could be as high as 50 ng/mL during 60-80 hours after AMI and remains detectable for up to 10-14 days post AMI. Therefore, circulating cTnI is a specific and sensitive marker for AMI. Clinical performance: Relative Sensitivity: 95.8% (95% CI: 91.5-97.9%) compared to a reference CLIA Relative Specificity: 99.7% (95% CI: 98.8-99.9%) Analytical sensitivity: The detection limit of cTnI is 1.0 ng/mL or greater in serum, plasma or whole blood specimen Cross-reactivity: No cross reactivity with 10 µg/mL skeletal muscle TnI, 2,000 ng/mL cardiac muscle TnT, 20 µg/mL cardiac muscle Myosin Dose hook effect: No hook effect was observed for cTnI at concentrations up to 3,521 µg/mL Interference: No interference was seen with 20 mg/dl Acetaminophen, 20 mg/dl Acetylsalicylic acid, 10.5 g/dl Albumin, 20 mg/dl Ascorbic acid, 1,000 mg/dl Bilirubin, 20 mg/dl Caffeine, 800 mg/dl Cholesterol, 200 mg/dl Creatinine, 20 mg/dl Gentistic acid, 1,000 mg/dl Hemoglobin, 600 mg/dl Oxilic acid, 1,600 mg/dl Triglycerides Shelf life: 24 months Individually sealed foil pouches containing: One cassette device One desiccant Plastic droppers Sample diluent (REF SB-R3002, 5 mL/bottle) One package insert (instruction for use) CTK Products at a Glance Insert MedlinePlus: Troponin Test Poster

Buy AccuTest Vitamin D Rapid Card Test (10 Tests) Online from Accurex. The Vitamin D test kit consists of 25 AccuTest Vitamin D individually packed test, devices in foil pouches, 25 pipettes for collecting 10 ul of whole blood, 25 lancets, 1 Buffer Vial (Buffer 5 mL) with stabilizers and, thimerosal, 1 Package Insert. Vitamin D Fast test kit is a rapid chromatographic immunoassay for the semi quantitative detection of Vitamin D levels in human blood/serum. This Vitamin D test provides a preliminary screening test result. INTENDED USE AccuTest Vitamin D is a rapid chromatographic immunoassay for the semi quantitative detection of Vitamin D levels in human blood/serum. This assay provides only a preliminary screening test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. The performance characteristics of this assay have not been established in a pediatric population. PRINCIPLE AccuTest Vitamin D is based on the principle of a competitive enzyme immunoassay. The assay is based on the competition for 25-OH Vitamin D present in blood/serum sample and Vitamin D present on the test line for fixed number of antibody-gold conjugate. Depending upon the concentration of Vitamin D in blood/serum, there will be free antibody-gold conjugate molecules that will bind to Vitamin D on the test strip and will show a colored line in the test line zone. A control line is present in the test window to work as procedural control. PRECAUTIONS 1. For in vitro diagnostic use only. 2. The test is designed for use with human blood/serum only. 3. Reagents must be at room temperature (8⁰C – 30 ⁰C). 4. Do not use if test device packaging is open or damaged. 5. Do not use the product beyond expiration date. 6. Handle all specimens as potentially infectious. Proper handling and disposal methods should be used according to good laboratory practices. 7. Read test results for 10 minutes as required. Results may deteriorate and may not be consistent after 10 minutes. 8. In order to avoid variable results, mix the blood sample thoroughly. 9. A serum sample subjected to repeated freeze thaw cycles may give variable results Direction for Use PROCEDURE 1. Remove the cassette from the sealed pouch and place it on a hard flat surface with the view window facing up (use the cassette as soon as possible). 2. Using a micropipette, add 10 µl of whole blood or 5ul of serum sample directly into the rectangular specimen well (marked with Red drop) of the cassette. 3. Add 3 full drops of Buffer into the square buffer well of the cassette (Do not move the cassette after addition of buffer). 4. Let the cassette sit for 10 minutes and read your results immediately. Results may deteriorate after the 10 minute mark. Other Info STORAGE AND STABILITY The test device should be stored at 8 ⁰C – 30 ⁰C and will be stable until the expiration date stated on the package. The product is humidity sensitive and should be used immediately after being open. INTERPRETATION OF RESULTS Match the color of the test line with the chart provided.
