This article introduces an overview of semiconductor immunity standards and testing methods. Types of Semiconductor Immunity Standards Semiconductor immunity standards are divided into two types based on the type of noise they address: one is for “Continuous Wave” standards, and the other is for “Impulse Wave” standards. The immunity standard for continuous waves is the … Read more
Diabetes occurs due to dysfunction of pancreatic β cells and insufficient biological effects of insulin (insulin resistance), leading to increased blood sugar and decreased insulin levels. The changes in serum insulin/C-peptide concentrations measured at fasting and 30 minutes, 1 hour, 2 hours, and 3 hours after oral glucose during an Oral Glucose Tolerance Test (OGTT) … Read more
In the field of in vitro diagnostics, the reagent instructions serve as a “guideline for action” that directs users on proper operation to ensure accurate and reliable test results. Among these, the description of instrument parameter configuration is a critical aspect. Today, we will delve into how to describe instrument parameter configuration in the instructions … Read more
