Quantitative urine culture is one of the most frequently requested tests in microbiology laboratories. An automated system for screening purposes is strongly needed to save technical staff time and obtain rapid results. Our study investigated 1.047 urine samples collected from inpatients and outpatients with a commercial vacutainer system (Becton Dickinson, Milan, Italy) and compared a second-g...

Diagnosis of urinary tract infection (UTI) is primarily done by microbiologic culture, which is time-consuming and can produce false-positives and false-negatives. Flow cytometry allows for rapid screening of many samples and eliminates culturing. We analyzed the Sysmex UF-1000i (TOA Medical Electronics, Kobe, Japan) for accuracy in identifying RBCs and WBCs, casts, bacteria, and epithelia. We ...

The precision of sodium, potassium, chloride, and bicarbonate analyses carried out by the AutoAnalyzer has been studied under routine laboratory conditions. From the results it is concluded that a further increase in precision is desirable.

Automatic performance debugging of parallel applications usually involves two steps: automatic detection of performance bottlenecks and uncovering their root causes for performance optimization. Previous work fails to resolve this challenging issue in several ways: first, several previous efforts automate analysis processes, but present the results in a confined way that only identifies perform...

Although automation was introduced into biochemistry in 1957 (Skeggs, 1957), it was not until 1963 that McNeil, Helrick, and Ferrari (1963) first described a mechanized technique forABO grouping. This was followed a few months later by a method employing the AutoAnalyzer continuous flow principle by which up to 40 samples per hour could be both ABO and Rh (D) grouped (Sturgeon, Cedergren, and M...

The XE-2100 is a new automated hematology analyzer developed by Sysmex Corporation. With consideration of medical analyzer requirements for the 21st century, this unit was developed to satisfy the following concepts and to cope with diversified laboratory needs. 1) Electronic network communication 2) Presentation of high level value-added information 3) Contribution to test cost control 4) Purs...

Sera left overnight in plastic AutoAnalyzer sample cups may give low calcium values; the effect is attributed to adsorption of calcium onto the walls of the vessel. The adsorption is brought about by a rise in the pH of the sera, and factors which promote the rise in pH increase the adsorption. This phenomenon is of practical importance because as much as 10% of the calcium in the serum may be ...
