The FactView HBsAg Strip is a diagnostic assay used for the qualitative detection of hepatitis B surface antigen (HBsAg) in human serum or plasma samples. Here's more information about this type of diagnostic test:
Purpose: The test is used for the diagnosis of hepatitis B virus (HBV) infection. HBsAg is a protein present on the surface of HBV particles and is the earliest serological marker of acute HBV infection. Detection of HBsAg indicates active HBV infection.
Principle: The FactView HBsAg Strip is typically an immunochromatographic assay that utilizes specific antibodies to capture HBsAg molecules in a patient's serum or plasma sample. The test is based on the principle of antigen-antibody binding, where HBsAg in the sample binds to specific antibodies immobilized on the test strip, resulting in the formation of visible test lines.
Components: The test kit usually includes test strips, sample droppers, buffer solutions, and desiccants. The test strips contain specific reagents and antibodies for capturing HBsAg from the serum or plasma sample.
Procedure: The test procedure involves collecting a small amount of serum or plasma from the patient and adding it to the sample well of the test strip. Buffer solution is then added, allowing the sample to migrate along the test strip. Results are typically visible within 15-20 minutes.
Interpretation: The appearance of colored lines on the test strip indicates the presence or absence of HBsAg in the patient's serum or plasma sample. A visible line in the control region indicates that the test is valid. An additional line in the test region indicates a positive result for HBsAg.
Sensitivity and Specificity: The FactView HBsAg Strip demonstrates high sensitivity and specificity for detecting HBsAg in serum or plasma samples. However, like all diagnostic tests, false-positive and false-negative results are possible and should be interpreted in conjunction with clinical findings.
Utility: The qualitative detection of HBsAg provides valuable information for diagnosing HBV infection, assessing disease status, and guiding patient management decisions. HBsAg positivity indicates active viral replication and infectiousness.
Limitations: While HBsAg testing is a valuable diagnostic tool, it has limitations, including the potential for false-positive results in low-prevalence populations and the inability to differentiate between acute and chronic HBV infection based solely on HBsAg positivity.
Overall, the FactView HBsAg Strip is an important tool for diagnosing HBV infection, allowing for timely intervention and management of patients with HBV-related liver disease. It aids in the prevention of HBV transmission and the implementation of control measures to reduce the burden of hepatitis B worldwide.
The HbsAg (Hepatitis B surface antigen) device is a medical tool designed to detect the presence of the hepatitis B virus surface antigen in blood samples. Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease. The device typically works by utilizing immunoassay techniques, where antibodies specific to the HbsAg antigen are used to capture and detect the antigen in the blood sample. This detection can be qualitative, indicating whether the antigen is present or not, or quantitative, providing information on the concentration of the antigen in the sample. These devices play a crucial role in diagnosing hepatitis B infection, screening individuals for the virus, and monitoring patients' response to treatment. Rapid and accurate detection of HbsAg is essential for timely intervention and management of hepatitis B infection to prevent complications and transmission of the virus.
VDRL (Venereal Disease Research Laboratory) is a test used to detect the presence of antibodies produced by the body in response to the bacterium Treponema pallidum, which causes syphilis. The VDRL test is a screening test for syphilis, and it's commonly performed on blood samples. The VDRL test typically involves mixing a patient's blood serum with a substance that mimics the antigens produced by the bacterium that causes syphilis. If antibodies to syphilis are present in the serum, they will react with these antigens, causing visible clumping (agglutination) in the test tube. The degree of clumping is then assessed visually or with the help of laboratory equipment. Strip tests for syphilis detection work on similar principles but are often designed for rapid and easy use. These strips contain specific antigens or antibodies that react with the patient's blood sample, producing a visible result that indicates the presence or absence of syphilis antibodies. The VDRL strip test, like other rapid diagnostic tests, offers quick results, making it valuable for screening purposes, especially in resource-limited settings or where timely diagnosis is critical. However, it's essential to confirm positive results with additional tests, as false positives can occur, especially in populations with low prevalence rates of syphilis.
These urine test strips are commonly used in healthcare settings, including clinics, hospitals, and laboratories, as well as for at-home testing purposes. They are designed to provide a quick and convenient method for screening for various substances, including glucose, in urine. Here's how they typically work: Sample Collection: A urine sample is collected from the patient. This sample is usually collected in a clean container and may be collected at any time of the day. Dipping the Strip: The urine test strip is dipped into the urine sample for a few seconds, ensuring that all the reagent pads on the strip are fully immersed in the urine. Reaction with Glucose: If glucose is present in the urine sample, it will react with the reagent on the strip. This reaction typically produces a color change on the reagent pad corresponding to the concentration of glucose in the urine. Interpretation of Results: After a specified reaction time (usually a few minutes), the color changes on the reagent pads are compared to a color chart provided by the manufacturer. This chart helps determine the approximate concentration of glucose in the urine sample. A "Glucose 1P" urine strip may indicate that it is specifically designed to detect glucose in urine and may have a single pad (1P) for detecting glucose. These strips are useful for screening for conditions such as diabetes mellitus, where elevated levels of glucose may be present in the urine. It's important to note that urine glucose testing using test strips provides qualitative results and may not be as accurate as laboratory-based quantitative measurements of glucose levels in blood. Therefore, any abnormal results obtained using urine test strips should be confirmed with further diagnostic tests, such as blood glucose measurement, for accurate diagnosis and management.
"Factview Urine Strip Glucose & Protein 2P" likely refers to a specific product or brand of urine test strip used for the qualitative detection of both glucose and protein in urine samples. These urine test strips are commonly used in healthcare settings for routine urinalysis to screen for various substances, including glucose and protein, which can indicate various health conditions when present in abnormal levels. Here's how they typically work: Sample Collection: A urine sample is collected from the patient. This sample is usually collected in a clean container and may be collected at any time of the day. Dipping the Strip: The urine test strip is dipped into the urine sample for a few seconds, ensuring that all the reagent pads on the strip are fully immersed in the urine. Reaction with Glucose and Protein: If glucose and protein are present in the urine sample, they will react with the respective reagents on the strip. This reaction typically produces color changes on the reagent pads corresponding to the concentrations of glucose and protein in the urine. Interpretation of Results: After a specified reaction time (usually a few minutes), the color changes on the reagent pads are compared to a color chart provided by the manufacturer. This chart helps determine the approximate concentrations of glucose and protein in the urine sample. A "Glucose & Protein 2P" urine strip indicates that it is specifically designed to detect both glucose and protein in urine and may have two separate pads (2P) for detecting each substance. These strips are useful for screening for conditions such as diabetes mellitus (glucose) and kidney disease or urinary tract infections (protein), where abnormal levels of these substances may be present in the urine. It's important to note that urine testing using test strips provides qualitative results and may not be as accurate as laboratory-based quantitative measurements of glucose and protein levels in urine. Therefore, any abnormal results obtained using urine test strips should be confirmed with further diagnostic tests for accurate diagnosis and management.

It is intended for use in medical institution as an aid for diagnosis and management of patients related to infection with hepatitis B as well for screening of blood donors or blood products PRINCIPLE Rapid HBsAb Test employs chromatographic lateral flow device. Colloidal gold conjugated surface antigen reactive to anti-HBs (sAg-Au) are dry-immobilized onto a nitrocellulose membrane strip. When the sample is added, it migrates by capillary diffusion through the strip rehydrating the gold conjugate. If present, anti-HBs will bind with the gold conjugated antigens forming particles. These particles will continue to migrate along the strip until the Test Zone (T) where they are captured by HBsAg immobilized there and a visible red line appears. If there is no anti-HBs in sample, no red line will appear in the Test Zone (T). The gold conjugate will continue to migrate alone until is captured in the Control Zone (C) from immobilized goat, anti-HBs antibody and aggregating in a red line, which indicates the validity of the test STORAGE Store the test device at 4 to 30°C. Do Not Freeze.
