Dry Blood Spot Paper Manufacturer,Supplier and Exporter in India

Dry Blood Spot Paper (Product Code: SLE/CL/48) is a bar-coded dry blood spot (DBS) card with 5 distinct pre-marked spots, used to collect blood for early infant diagnosis of HIV. It collects blood and preserves it for later nucleic acid analysis, with stated DNA stability of at least 24 months. The spots are pre-perforated (pre-punched), which makes it quicker to release sample discs for PCR processing in the receiving laboratory. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, which serves health programmes as a lab consumables supplier in India.

Specifications

Typical Use

At the collection point, the health worker records the patient details against the card’s barcode, punctures the infant’s heel or the side of a finger, and lets one large drop fall onto each pre-marked circle so it soaks through the paper. Drops should not be layered or pressed on, and the filter area should never be touched with fingers or gloves. The card is then dried flat, away from sunlight, before being packed for transport to the testing laboratory.

In the laboratory, the pre-perforated spots can be released and placed into extraction tubes or plate wells, reducing the time spent punching discs and the risk of carrying material between samples. Molecular labs that run PCR equipment in India for infant diagnosis rely on the barcode to link each result back to the right child and collection site.

Frequently Asked Questions

How many spots are on each card?
Five distinct pre-marked spots.

How long does the sample remain usable for DNA testing?
The listing states a minimum of 24 months for DNA. This assumes spots are dried and stored properly; stability for other analytes is not stated.

Is each card individually identified?
Yes, the cards carry bar coding so each sample can be traced to its patient record.

Do I still need a DBS punch?
The spots are pre-perforated to make processing easier. Some laboratories still use a punch as part of their method, so follow your own procedure.

Can the card be used for tests other than infant HIV diagnosis?
The listing names HIV infant early diagnosis. Any other use should be validated by the testing laboratory; contact us to discuss your application.

How should unused cards be stored?
Storage conditions for unused cards are not given in the listing. Ask us for handling guidance with your order.

Can you supply programme-scale quantities?
Yes. Tell us the card quantity, delivery points and timeline, and we will prepare a quotation for India or international markets.
