Presumptive Blood Tests

This presumptive blood test is designed to be a simple, one shot test for the presence of blood. This portable test will fit in your pocket and allows you to test suspect stains without taking the time to mix chemicals. Simply place a small quantity of the stained material, or a portion of a swabbing of the stain, into the kit and crush the color-coded vials in sequence. Their formulation has long been accepted by the courts and proven in the field. This kit will automatically let you know if it has expired, thus minimizing the chance of a negative reading. > More

Phenolphthalein is one of the most commonly used chemicals in the field and laboratory to indicate the presence of blood. Our pre-packaged kit contains all the reagents and supplies to conduct a presumptive blood test. There is a “known” sample to let the user know the kit is working. Packaged in a plastic box. > More

Many investigators use O-Tolidine as a presuptive test after the Phenolphthalein Presumptive Blood Test. A positive presumptive result yields a blue color. Packaged in a plastic box with all the necessary premixed chemicals and supplies to conduct a O-Tolidine Blood Test. The premixed chemicals are packaged in plastic dropper bottles. A known blood standard is included to monitor the results. > More

Many investigators use this highly sensitive test as confirmatory test after the Phenolphthalein Presumptive Blood Test. A positive presumptive result yields a deep blue color. Packaged in a plastic box with all the necessary premixed chemicals and supplies to conduct a Leucocrystal Violet Blood Test. The premixed liquid reagents are packaged in plastic dropper bottles. A known blood standard is included to monitor the results. > More

The Foren-Stix Applicators are designed to provide the crime scene investigator with the ability to conduct presumptive chemical fluid field tests utilizing simple methodology and minimum equipment. These applicators feature an absorptive sampling pad on the end of a plastic tube containing glass crush vials with premixed chemical reagents. Simply remove the cardboard cap, moisten the pad with the included distilled water, rub the pad on the suspected stain to transfer a sample to the pad, break the crush vials in the plastic tube, gently squeeze, and observe a color change to indicate a positive presumptive reaction. Each kit contains eight tests, a dropper bottle of distilled water and instructions for use. > More

Heme-Stix were developed to provide the investigator with a fast, convenient, sensitive, and reliable presumptive test to identify blood at the crime scene. Each test is a compact, self contained system consisting of two glass ampules inside a plastic tube. These tests are similar to the well known tube tests commonly seen in drug tests. Positive reaction will yield a deep blue color. Contains 10 tests and 10 sampling swabs with instructions. > More

Hema-Test provide a fast and easy presumptive blood test. Each Hema-Test consists of a stiff plastic strip with an absorption patch on one end that contains the test reagents. The test is based upon the pseudo-peroxidase action of hemoglobin which catalyzes the reaction of Tetramethyl-benzedine and organic peroxide. The strip will turn a dark blue color when the end is dipped into a moistened stain that contains blood. The strip can be rubbed on a dry stain, then add a drop of water to activate the reagent. > More

Rapid screening test for the verification of human blood. Test provides a positive or negative result for human blood within 2 min. Two part test consists of a liquid filled collection vial with integrated swab and an easy-to-read test device. > More
