Liquid level detection (LLD) is necessary for eliminating carry-over of needle's outside by limiting the depth the needle probes into liquid in auto clinical laboratory analyzers. This paper listed various demands of liquid-handling system under different situations; reviewed various LLD techniques, such as capacitive, air pressure, mechanical vibration, ultrasound, light reflection, CCD imaging etc.; briefly introduced the working principles, features, and limitation of the LLDs; and recapitulated the characteristics of contact and non-contact LLDs. Lastly, the next generation technique of LLD is prospected.

Traditional Chinese medicine (TCM) and Western medicine have the common purpose and can complement each other, though they belong to different medical systems. Laboratory medicine can provide the scientific bases for modernization and standardization of TCM by offering elaborate and objective laboratory data. Fully playing the role of laboratory medicine in TCM diagnosis and treatment will not only be beneficial to the rush of TCM out of China toward the world, and also be favorable to the innovating and developing of laboratory medicine in integrative medicine.

The laboratory diagnostic strategy for human immunodeficiency virus (HIV) is a process to accurately detect HIV patients through a combination of available HIV tests. Laboratory tests for HIV infection are mainly serological antibody and antigen testing and HIV RNA testing. With the update of testing reagents, the sensitivity and specificity have improved substantially and the window period of detection has shortened, but there is a risk of false positives. Various guidelines have recommended different diagnostic strategies for different target populations and different prevalence regions to guide patients to confirm the diagnosis and receive standardized antiretroviral therapy as early as possible. How to refer to the diagnostic strategies, reduce false positives and shorten the window period while increasing the detection rate is an urgent issue for laboratories to address. This article describes the characteristics and advantages and disadvantages of testing methods related to HIV infection from the perspective of laboratory diagnostic strategies, as well as the impact of the development of treatments on diagnostic strategies, in order to provide theoretical support for the practical application of HIV diagnostic strategies.

Hepatitis type E virus (HEV) infection is a common cause of acute viral hepatitis in China, and its etiological diagnosis relies on laboratory detection. Therefore, this article introduces the HEV RNA, HEV antigen, anti-HEV IgM, and IgG detection methods and their diagnostic application value. In addition, it also discusses the current international diagnostic standard and HEV infection presentation.
