Industry news

Dried blood spot (DBS) technology is a very simple and inexpensive technique for collecting drop(s) of whole blood on filter paper. DBS has been in existence for almost 50 years but has gained interest recently due to advancements in technologies that enable sensitive and reliable methods for collecting quantitative data from a drop of blood samples.

Advantages of dried blood spot testing:

  • Minimally invasive technique and can be self-collected by finger prick.
  • Dried blood inactivates pathogens and lowers the biohazard risk.
  • No centrifugation required.
  • Few drops (µL) of blood needed.
  • Easy to split spots between sites.
  • An ideal method for lab animals.
  • Small size and can be stacked and shipped by regular mail.
  • Stable at ambient temperature if refrigerator space is limited.
  • Correlations to serum or plasma samples exceed 95%.

Dried blood spot immunoassays

MenoCheck:

An FDA cleared, novel blood test to help assess a woman’s menopausal status and assists in estimating the time to the final menstrual period. Dried blood spot sampling means that physicians can mail the sample collection devices to the patients that are remote. It also allows for easier serial sample collections and it greatly simplifies the storage, preparation, and transportation of samples. Learn more about the DBS AMH testing and the validation of the DBS AMH ELISA.

Dried Blood Spot AMH ELISA

Ansh Labs

Dried blood spot specimens stability makes it a practical alternative to venous blood. It opens new possibilities in AMH testing, such as comparison of historical to current patient results; simplified blood sampling for patients in remote locations or for those who are homebound. Instead of traveling to a clinic to get blood drawn, a blood spot sample can be taken at a convenient site and mailed to a laboratory.

MenoCheck picoAMH ELISA

Ansh Labs

The MenoCheck® picoAMH ELISA is FDA cleared for in vitro diagnostic use as an aid in the determination of menopausal status in women between 42 and 62 years of age. This is the only AMH test with the sensitivity to quantify declining AMH concentrations in women who are entering their menopausal transition.

ELISAEnzyme-linked immunosorbent assays (ELISA), also known as enzyme immunoassays (EIA), are used for the detection and quantification of proteins, peptides and antibodies in a sample. ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits. Find the best ELISA kits and products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.ImmunoassayImmunoassays are laboratory tests that utilize antibody-antigen interactions to detect specific substances. They are widely used in diagnostics for detecting diseases, drug testing, and environmental monitoring. These assays offer rapid, sensitive, and precise detection of biomarkers, making them invaluable in clinical and research labs.
