The new swab, designed for infants up to six months, produces increased fluid retention through the tip allowing for faster collection of infant saliva. Samples collected using the Salimetrics Infant Swab (SIS) can be tested for cortisol, cotinine, testosterone, sIgA, alpha-amylase, CRP, IL-1beta and Chromogranin A.
The diameter of the Salimetrics Infant Swab has been increased to 6.3 mm. This allows the new swab to access more saliva in the newborn’s mouth and thereby increase the collection volume. Typical recovered sample volume is 200-1000 microliters (µL).
“The larger diameter produces increased rigidity, improving directional orientation during collection,” explained Hans Schroeder, CEO of Salimetrics.
The length of the infant swab allows the collector to hold one end of the swab for young children with risk of choking.
“Salimetrics’ Infant Swabs are used in studies to detect elements of stress in newborns,” said Jon Peterson, Ph.D., FACB, Salimetrics principal scientist. “The Salimetrics Infant Swab is tested against interference by a number of analytes and can be relied upon to produce accurate salivary results of stressors that have an impact on infant health.”
As with all other Salimetrics swabs, the infant swab can be stored utilizing the Salimetrics Swab Storage Tube, and can be frozen at -80C. Flow rate for the infant swab and all Salimetrics swabs can be calculated by recording the collection time and weight of the Salimetrics swab before using a centrifuge to release saliva.
The improved Salimetrics Infant Swab comes complete and ready to collect, individually packaged with printed instructions. The SIS can be ordered by phone or fax, or through any Salimetrics distributor.
Salimetrics also offers training courses on saliva collection, including the new infant swab. These classes show how to incorporate salivary biomarkers into research and give insight into proper collection and handling methods and techniques. “Proper technique is the key to better, more accurate results with salivary biomarkers,” Dr. Peterson said.
