Presumptive Blood Test Kit
Presumptive Blood Test Kit (Product Code: SLE/CH/170) is a phenolphthalein-based test kit used to check materials for the presence of blood in forensic science and chemistry teaching labs. It includes instructions, a blood standard and reagents to complete 30 tests, and shows students why a screening result must be followed by further serology tests. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a hands-on chemistry experiment kit for classrooms in India and abroad.

What Is the Presumptive Blood Test Kit Used For?
A typical lesson starts with the blood standard, so students first see what a positive reaction looks like before they test unknown samples such as stained cloth, paper or wood prepared by the teacher. They then apply the reagents to each sample in the order given in the instructions and record whether the characteristic pink colour appears. Running a known negative, such as an unstained piece of the same material, beside every unknown builds the habit of using controls and opens a discussion of false positives.
The kit is also a clear way to show the limits of a screening test. Because the result cannot separate animal from human blood and further serology tests are needed, students learn why forensic laboratories treat a presumptive positive as a lead rather than proof. For departments that buy through a lab consumables supplier in India for recurring practicals, the 30-test quantity helps in working out how many kits a term of classes will need.

Frequently Asked Questions
How many tests can be run with one kit?
One Presumptive Blood Test Kit contains reagents to complete 30 tests, together with instructions and a blood standard. Larger classes or repeated sessions across a term will need additional kits, so plan quantities before ordering.
What is included in the Presumptive Blood Test Kit?
The Presumptive Blood Test Kit includes instructions, a blood standard and the reagents for the test. General items such as gloves, swabs and sample materials are not listed as included and should be arranged separately.
Can the test show whether blood is human?
No. The phenolphthalein test in the Presumptive Blood Test Kit does not distinguish between animal and human blood, which is an important teaching point about the limits of presumptive methods in forensic work.
Does a positive result prove that a stain is blood?
No. A positive result from the Presumptive Blood Test Kit indicates that blood may be present; further serology tests are needed to confirm the finding, which is why forensic laboratories treat it as a lead rather than proof.
What is the shelf life of the reagents?
The shelf life of the Presumptive Blood Test Kit depends on the chemicals, their grade and storage conditions; ask us for the expiry date of the batch you are quoted before planning a long storage period, and keep reagent containers capped.
Who supplies the Presumptive Blood Test Kit?
Jain Scientific Equipments Private Limited (ScienceLab), Ambala, Haryana, India, supplies the Presumptive Blood Test Kit to schools, colleges and training centres in India and international markets; include the destination country in your enquiry so shipping can be quoted.
