The NT-proBNP Rapid Test is intended for the qualitative determination of NT-proBNP in human whole blood/Serum/Plasma. Measurement of NT-proBNP values is useful in the diagnosis and assessment of severity of heart failure.
N-terminal pro-brain (or B-type) natriuretic peptide (NT-proBNP) is produced predominately by the cardiac ventricular myocytes. It is released in response to volume expansion and filling pressure and is involved in maintaining intravascular volume homeostasis. After synthesis, the peptide is cleaved first to proBNP and subsequently to BNP (active form) and NT-proBNP(inactive form). Natriuretic peptide (NP) levels (BNP and NT-proBNP) are widely used in clinical practice and cardiovascular research as a diagnotic tool for the occurrence and severity of heart failure (HF) and coronary syndrome. Elevated plasma levels of BNP and NT-proBNP have been observed at times of cardiac stress and damage. It has also been shown that increased NP values in patients with renal dysfunction can suggest the presence of cardiac disease. Low circulating NP levels have been observed in obese people, however the prognostic capacity of these biomarkers were not affected for those patients. In summary, NP levels are quantitative plasma biomarkers of an accurate diagnosis of heart failure. Measurements of NP levels may help in risk stratification of patients suffering heart attacks in emergency care and in accurate and rapid diagnosis of heart failure in primary care.
• Rapid test cassette with desiccant

• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE.
Sample Collection&Storage
• The NT-proBNP Rapid Test is intended for use with human whole blood, serum, or plasma specimens only.
• Only clear, non-hemolyzed specimens are recommended for use with this test. Serum or plasma should be separated as soon as possible to avoid hemolysis.
• Perform testing immediately after specimen collection. Do not leave specimens at room temperature for prolonged periods. Serum and plasma specimens may be stored at 2-8°C for up to 3 days. For long term storage, specimens should be kept below -20°C. Whole blood collected by venipuncture should be stored at 2-8°C if the test is to be run within 2 days of collection. Do not freeze whole blood specimens. Whole blood collected by fingerstick should be tested immediately.
• Containers containing anticoagulants such as EDTA, citrate, or heparin should be used for whole blood storage.
• Bring specimens to room temperature prior to testing. Frozen specimens must be completely thawed and mixed well prior to testing. Avoid repeated freezing and thawing of specimens.
• If specimens are to be shipped, pack them in compliance with all applicable regulations for transportation of etiological agents.
• Icteric, lipemic, hemolysed, heat treated and contaminated specimens may cause erroneous results.
Bring tests, specimens, and/or controls to room temperature (15-30°C) before use.
1. Remove the test from its sealed pouch, and place it on a clean, level surface. Label the device with patient or control identification. For best results the assay should be performed within one hour.
2. Transfer 3 drops of whole blood/serum/plasma to the specimen well (S) of the device with the provided disposable pipette, and start the timer.
OR
Allow 3 hanging drops of fingerstick whole blood to fall into the center of the specimen well (S) of the test device, and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.
3. If the test fails to migrate across the membrane after 1 minute, add 1 drop of buffer to the specimen well (S).
4. Wait for the colored band(s) to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
