Review Summary
Become a proficient investigator with Hemastix Blood Test Strips, a pack of 50, designed to accurately detect the presence of hemoglobin in various substances. These 3-inch plastic strips are equipped with a specialized blood reagent material at the tip, engineered to identify the peroxide-like activity of hemoglobin.
To use, simply glide the Hemastix across a moistened stain or a swab carrying a suspected dried blood sample. The reagent-coated tip will undergo a color transformation, turning a shade of green if hemoglobin is detected. This color change is not just a simple positive or negative indicator; it provides a measure of the level of hemoglobin present in the sample.
To interpret the results, compare the color reaction to the chart provided on the side of the bottle. This will help you determine the concentration of hemoglobin in the sample. If the reaction is positive, it's recommended to photograph the strip next to the substance to document the reaction, and retain the strip as evidence.
When collecting the blood sample, ensure to use a swab for optimal results. Each bottle comes with 50 test strips, designed to maintain their effectiveness for approximately a year from the date of manufacture.
While expired Hemastix may still react to the presence of blood, they are best utilized for training purposes. It's important to note that Hemastix does not distinguish between human and animal blood.
Whether you're a professional in the field or a student in training, Hemastix Blood Test Strips are an essential tool for accurate and efficient blood detection.
