Blood Glucose Meter
Keeping an accurate idea of your blood glucose levels is an integral part of successful diabetes management. Blood glucose meters allow you to do this.
Choosing the right meter will depend on the products available to you, the cost of test strips (if you need to buy you our own)
How easy are blood glucose meters to use?
This will depend on the design interface favoured by the manufacturer, but some blood glucose monitors are definitely easier to use than others. For instance, some meters require a smaller drop of blood to give a reading and others have easier to navigate results and menus.
When choosing a meter, you may need to decide whether you need more features or whether you need a meter that has advanced features but is simpler to use. Investigate the process before purchasing and speak to as many peers and experts as possible.
How long do tests take using blood glucose meters?
Most meters don’t take more than a minute to provide accurate blood sugar level results. For most people, and in the case of most meters, speed of testing will not really be an issue
COVID-19 IgM/IgG
COVID-19 IgM/IgG device is a chromatographic immunoassay kit for the rapid and differential detection of immunoglobulin M (IgM) and immunoglobulin G (IgG) against COVID-19 using serum, plasma and whole blood.
Specifications
- Store at 2~30℃
- Specimen : serum, plasma, whole blood
- Testing time : 10 mins
- Shelf life : 24 months after its manufacture date
- Sensitivity : 50% at Day 1~6, 91.7% at after Day 7
- Specificity : 97.5%
- Accuracy : 95.2% at Day 1~6, 96.5% at after Day 7
Assay procedure
Capillary blood is used to do the test, prick the finger and collect the blood by a capillary tube. And then, load the blood onto the sample well (S) of the test device.
Reading and interpretation of results
- Negative: ONLY one band in the control line (C). No COVID-19-specific IgM and IgG were detected. Re-test in 3-5 days if COVID-19 is suspected.
- IgM Positive: two bands appear in the test line (T) and control line (C) in the left side of device.
- IgG Positive: two bands appear in the test line (T) and control line (C) in the right side of device.
- IgG and IgM Positive: each two bands appear in the test line (T) and control line (C) in both side of device.
- Invalid result: If at 15 minutes, the red band does not appear in the control line (C), the result is considered invalid. If the test is invalid, a new test should be performed with a new patient specimen and a new test device.
Limitations of the test
GenBody COVID-19 IgM/IgG is designed for the detection of IgM and IgG antibodies against novel coronavirus (2019-nCoV). This kit can provide a fast and simple results but, do not completely exclude the possibilities of false positive or false negative results caused by various factors. For confirmation, please make a final decision with clinical symptoms, other testing results, and doctor’s assessment, collectively.
- GenBody COVID-19 IgM/IgG is only provided for use by clinical laboratories or to healthcare workers for point-of-care testing, and not for at home testing.
Instructions for use will contain the following information
- This test has not been reviewed by the FDA.
- Negative results do not rule out SARS-CoV-2 infection, particularly in those who have been in contact with the virus. Follow-up testing with a molecular diagnostic should be considered to rule out infection in these individuals.
- Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status.
- Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.
- Not intended for the screening of donated blood.
Cross-reactivity/analytical specificity
- Materials
- Substance to be tested in this experiment: listed in the Table 1.
- Testing device: GenBody COVID-19 IgM/IgG (Lot No.:FJ001).
- Methods
- The listed substances or anti-sera/plasma were used as the specimens of the testings. 10 ul of each material was loaded into the kit.
- Test procedure was fully followed by the manual of GenBody COVID-19 IgM/IgG.
- Results (table 1): As shown in table 1, all of the listed substances did not affect the proper reaction of the kit (not cross-reactive).
