Arden grating test scores were obtained for 100 normal subjects under standardised testing conditions. While previously published ranges of interocular conguity were corroborated, a significant increase in test scores with increasing age was noted. This effect of age has not been previously reported. Physiological considerations suggest that such age dependency might have been expected. It is s...

with specific tumor markers .So, tumor markers Ca 15-3, Ca19-9, Ca 125, and CEA were fluctuated in normal ranges. Serum levels of alphafetoprotein (a-FP) were significantly elevated reaching the plateau of 392 iu/ ml (normal ranges: <9.5 iu/ml), supporting the sonographically evoked opinion of underlying malignancy. Except that AST (62 IU/L), ALT (73 IU/L) and LDH (309 IU/L) were mildly increased.

OBJECTIVES To study 2 h plasma concentrations of the first-line tuberculosis drugs isoniazid, rifampicin, ethambutol and pyrazinamide in a cohort of patients with tuberculosis in Denmark and to determine the relationship between the concentrations and the clinical outcome. METHODS After 6-207 days of treatment (median 34 days) 2 h blood samples were collected from 32 patients with active tube...

AIMS Three-dimensional (3D) speckle tracking echocardiography (3DSTE) has been shown to be an accurate and reliable clinical tool for the evaluation of global and regional left ventricular (LV) function through strain analysis, but the absence of normal values has precluded its widespread use in clinical practice. The aim of this prospective multicentre study was to establish normal reference v...

BACKGROUND Some parents are requesting aluminum testing in their children with developmental issues. Although aluminum can be measured in plasma, serum, or urine, there is scant scientific information about normal ranges. We sought to determine the basis for laboratory reference ranges and whether these ranges are applicable to children. METHODS From texts, published lists, and Internet sourc...

Most reference ranges are not considered sex-age specific differences. We collected about 700,000 health examination data with 24 items to estimate sex-age specific clinical reference ranges. We proposed nonlinear optimization method as a new method compatible with NCCLS guideline. All items showed sex-age specific differences of reference ranges. Especially, hepatic functions in young aged men...

BACKGROUND The Clot Signature Analyzer (CSA) was designed to assess global hemostasis as a screening assay using non-anticoagulated whole blood. Three different measurements are produced by the instrument: platelet hemostasis time (PHT), clot time (CT), and collagen-induced thrombus formation (CITF). OBJECTIVES The purpose of the present study was to determine normal ranges for these measurem...
