Dedicated analyzer for the Macroduct System for total electrolyte analysis of sweat samples.

Interfacing perfectly with Macroduct, Sweat-Chek brings simplicity and economy to the analytical phase of the sweat test.

A truly practical sweat testing system is now within the means of small hospitals, local clinics, or private practitioners. Larger clinics and hospitals need no longer tie down personnel and resources with the tedious and error-prone pad absorption procedure when the Wescor method is so simple, safe, and accurate! While clinicians have traditionally used sweat chloride or sweat sodium ion assay, sweat conductivity is a proven method of sweat analysis. It is a simple and reliable indicator to confirm or exclude the physician's clinical diagnosis of cystic fibrosis.

Sweat•Chek™Analyzer

Sweat-Chek is a dedicated sweat electrolyte analyzer for use with the Macroduct® Sweat Collection System. Thousands of satisfied customers admit that the Sweat-Chek is easy-to-use, reliable and accurate. The co-inventor of the QPIT method, Dr. Lewis E. Gibson (1927-2008), was a firm supporter of the Macroduct/Sweat-Chek method, who stated:

"[Sweat-Chek]...gives results that are every bit as reliable as an analysis for sodium or chloride."

Sweat-Chek brings simplicity and economy to the analytical phase of the Macroduct sweat test for the laboratory diagnosis of cystic fibrosis. This truly practical sweat testing system is now within the means of small hospitals, local clinics, or private practitioners.

How it works?

Sweat samples are collected in Macroduct using the normal procedure. A syringe is attached to the end of the microbore tubing before the tubing is uncoiled and severed from the collector body. The end of the microbore tube is then attached to the inlet nipple of the Sweat-Chek conductivity cell.

A separate length of clean microbore tubing is attached to the outlet nipple of the cell to act as a take-up reservoir.

The specimen is transferred into the cell by moving the syringe plunger. When the specimen contacts both cell electrodes (less than 10 microliters are required), the conductivity of the specimen is measured, converted to equivalent NaCl molarity, and the result displayed.

The conductivity cell is temperature-controlled for stable calibration and operation. A stable reading obtains in about 10 seconds as the specimen equilibrates to the cell temperature. The digital readout is calibrated in units of molarity (mmol/L) representing the molar concentration of a NaCl solution equivalent in conductance to that of the sample.

The specimen can be drawn back into the cell for repeat measurement, or it can be expressed into a storage cup for subsequent corroborative analysis by any microanalytical procedure including anion assay, cation assay, osmolality assay, or electrical conductivity if desired.
