Phadebas amylase test kits.

The observation by Hafkenscheid (1) thatPhadebas Amylase Test kitswith bovine serum albumin (BSA) gave lower results than those without BSA is, as he infers, evidently caused by differences between the standard curves supplied by the manufacturer. We found rather better agreement for plasma assays between the oldand new-formulation tablets (2). However, we routinely check the calibration curve ...

Test and Diagnostics

Multiple techniques and tools, including static analysis and testing, should be used for software assurance. Fuzz testing is one such technique that can be effective for finding security vulnerabilities. In contrast with traditional testing, fuzz testing only monitors the program for crashes or other undesirable behavior. This makes it feasible to run a very large number of test cases. This art...

Sigma diagnostics: pioneer of kits for clinical chemistry.

Having graduated in chemical engineering from Washington University in St. Louis in September, 1939, I started work in its Biochemistry Department as a research assistant and as a laboratory assistant to medical students who were studying biochemistry. Alter 2 years, I left the University to work for a milling company in Kansas City in a program that involved enriching flour with vitamins. My j...

HIV Rapid Diagnostic Test Inventories in Zambézia Province, Mozambique: A Tale of 2 Test Kits

Background The first pillar of the UNAIDS 90-90-90 goal seeks to accurately identify persons living with HIV (PLHIV), a process that is predicated on facilities having the necessary HIV tests available to perform the task. In many rural settings, the identification of PLHIV is accomplished through a two-step process involving the sequential use of 2 separate rapid diagnostic tests (RDTs)....
