Singclean Interleukin-6 (IL-6) Test Kit (Fluorescence Immunochromatography) to help monitor inflammatory responses
1. Introduction
Creatine Kinase-MB (CK-MB) is one form of Creatine Kinase (CK). The normal range in blood is less than 5ng/ml, which is not detected in normal blood, or only trace CK-MB is present. Only after myocardial injury, the myocardial cell ruptured and creatine kinase released from the myocardial cell and absorbed into the blood, can the creatine kinase be detected in blood sample, which indicates the presence of myocardial injury. Singclean® Creatine Kinase Isoenzyme MB (CK-MB) Test Kit (Fluorescence Immunochromatography) is used for quantitative determination of Creatine Kinase Isoenzyme MB (CK-MB) range in human serum, plasma or whole blood samples in vitro as the mark of myocardial infarction.
2. Indications for Use
This kit is used for the quantitative determination of Creatine Kinase Isoenzyme MB (CK-MB) in human serum, plasma or whole blood samples in vitro.
There are four isozyme forms of Creatine Kinase (CK): muscle type (MM), brain type (BB), mixed type (MB) and mitochondrial type (MiMi), among which MB type is mainly present in myocardial cells. In myocardial infarction, creatine kinase increases within 6 hours of onset, peaks at 24 hours, and returns to normal within 3~4 days. Among them, Creatine Kinase Isoenzyme MB has high diagnostic specificity, so it has become one of the markers of myocardial infarction.
3. Who Should Have the Creatine Kinase-MB (CK-MB) Test ?
Unnormal range of MB (CK-MB) in blood is the sign of myocardial infarction.
If you have symptoms like angina, arrhythmia, heart failure and compressive pain or tightness in precordium that lasts more than 30 minutes and it is suggested to have a MB (CK-MB) testing.
By testing the MB (CK-MB) in blood, we can know whether a person's MB (CK-MB) range is more than 5ng/ml, which means the likelihood of myocardial infarction. For those people whose MB (CK-MB) range is more than 5ng/ml, it shows they have the risk of myocardial infarction, and they should go for a timely medical treatment.
4. Features

c) Blank limit: not higher than 2.5ng/mL;
d) Precision:
In-batch precision: The coefficient of variation (CV) is not more than 15%;
Precision between batches: The relative range between batches is not more than 15%.

7. Specimen Collection
1. Human serum, plasma or whole blood samples; other body fluids and samples may not give accurate results.
2. Venous blood or fingertip blood should be collected under sterile conditions. It is recommended to use human serum or plasma for testing.
3. Anticoagulation with EDTA, sodium citrate or heparin is recommended for plasma and whole blood samples.
4. After the clinical blood samples are collected, the test must be completed within 4 hours at room temperature; serum and plasma can be stored at 2~8°C for 3 days and stored below -20°C for 5 months. Whole blood samples should not be frozen and stored at 2~8°C for 3 days. Avoid heat inactivating samples, and hemolyzed samples should be discarded.
5. Samples must be returned to room temperature before testing. Refrigerated samples need to be completely thawed, rewarmed, and evenly mixed before use. Do not freeze and thaw repeatedly.
8. Test Procedure
Please read the instructions of the test kit and the manual of the fluorescence immunoanalyzer carefully before use.
a) Bring the test kit and sample to be tested to room temperature.
b) Make sure the ID card matches the batch number of the kit, and insert the ID card into the card reading area of the instrument to read the information.
c) Open the inner package of the test kit, take out the test card; draw 70μL of serum plasma sample, drop vertically to the sampling place of the test card, and start timing; draw 70μL whole blood, drop vertically to the sampling place of the test card, and immediately add 1 drop of whole blood diluent at the sampling place and start timing.
d) After adding the sample, click "Start Test" on the screen of the fluorescence immunoanalyzer, and the test card will react at room temperature for 10 minutes; insert the test card into the test card slot of the fluorescence immunoanalyzer, and the instrument will automatically test the test card; The test results can be seen on the display screen of the fluorescence immunoanalyzer. Click "Print" on the screen to print the results.
9. Positive Judgment Value or Reference Interval
Normal reference value: <5ng/mL
Due to differences in geography, race, gender and age, it is recommended that each laboratory establish its own positive judgment value or reference interval.
10. Interpretation of Results
(For reference only, not used as clinical diagnostic criteria, test results need to be combined with other clinical and laboratory data for clinical diagnosis)
| Content of CK-MB (ng/mL) |
Clinical application advice |
| 0-5 |
Normal level |
| >5 |
It is suggested that the patient is at risk of myocardial infarction. Note: CK-MB exceeds the normal level within 4~8 hours after myocardial infarction; peaks within 12~24 hours; and returns to normal level in about 3 days. |
11. Limitations
a) This test kit is only for the test of human serum, plasma or whole blood samples. Abnormal hematocrit samples have an impact on the results of the whole blood test. The test results of serum, plasma and whole blood are not significant difference when the hematocrit is between 21% and 48%.
b) The test results need to be combined with other clinical and laboratory data, and if the CK-MB test results do not match the clinical assessment, further testing is required.
c) False positive results may be caused by: cross-reaction of antibody-like components in the blood; some nonspecific components in blood have similar antigenic determinants to capture fluorescent-labeled antibodies.
d) Hemoglobin, triglycerides and bilirubin in the blood sample can interfere with the test results, with the maximum allowable concentrations being 5g/L, 10g/L and 0.2g/L, respectively.
e) False negative results may be caused by: some unknown components shield the antigenic determinants from binding to the antibody; the unstable CK-MB antigen gradually degrades with time and temperature and cannot be recognized by the antibody. Effective test results depend on good reagent and sample storage environment.
f) Other factors, including technical reasons, operational errors and other sample factors, may also cause errors in test results.
