All Services Microsampling Platform

Dried Blood Spot.

A low-invasive microsampling alternative to venipuncture. Fingerprick or heel-prick collection onto filter paper, room-temperature transport, and high analyte stability — enabling diagnostic testing from just 25–75 µL of capillary blood.

Why DBS

Unique Properties.

Low Invasiveness Ideal for children, elderly, needle-averse patients, and athletes avoiding training abstinence.
Minimal Volume Just 25–75 µL of blood. Critical for newborns and patients needing frequent monitoring.
Home Collection No medical personnel required. Enables population-scale screening in resource-limited settings.
Analyte Stability Drying inhibits metabolic processes. No special storage or transport conditions required.
Reduced Infectivity Drying inactivates HIV and prevents HBV transmission, reducing biohazard risk.
Limitations: Haematocrit-dependent results · Limited test quantity per card · Specialist equipment required
Contraindications: Dehydration/overhydration · Compromised circulation · Skin lesions at site · Coagulation disorders · Heel puncture for infants <10 kg

Application Areas.

Metabolic & Nutritional

Amino acids, acylcarnitines, vitamins, trace elements, bile acids, carnitine, creatinine, homocysteine, and haemoglobin variants.

Newborn Screening

Early detection of inborn metabolic disorders: maple syrup urine disease, tyrosinaemia, citrullinaemia, organic acid disorders, and fatty acid oxidation disorders.

Endocrinology

Hormones, thyroid function markers (TSH, free thyroxine), and steroid panels from capillary microsamples.

Toxicology & Pharmacology

Therapeutic drug monitoring, forensic and clinical toxicology, pharmacokinetic studies, and psychoactive substance detection.

Infectious Disease Serology

Hepatitis B/C, HIV, measles, mumps, polio, RSV, Borrelia (Lyme), syphilis, and SARS-CoV-2 antibody detection.

Emerging Areas

Metabolic syndrome studies, environmental contamination monitoring, prostaglandins, cytokines, tumour markers, and animal research applications.
