Detection of hydatid antigen in urine by countercurrent immunoelectrophoresis

Detection of hydatid antigen in urine by countercurrent immunoelectrophoresis.

Hydatid antigen was demonstrated for the first time in the urine of patients with hydatid disease by countercurrent immunoelectrophoresis (CIEP). The antigen was detected in the concentrated urine of 7 of 16 (43.75% positive) patients with surgically confirmed hydatid disease, 4 of 10 (40% positive) patients with ultrasound-proven hydatid disease (daughter cysts or prominent septation and hydat...

Anomalous results using countercurrent immunoelectrophoresis for the detection of pneumococcal antigen in Bactec blood culture media.

On examination of Bactec blood cultures for pneumococcal antigen by countercurrent immunoelectrophoresis the consistent presence of a non-specific protein band caused problems with the interpretation of results, even in laboratories experienced in performing countercurrent immunoelectrophoresis. When the Bactec blood culture system is used, countercurrent immunoelectrophoresis should not be rel...

hydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction

hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...

Limitations of countercurrent immunoelectrophoresis (CIE) in the diagnosis of empyema.

Countercurrent immunoelectrophoresis: improved detection of pneumococcal capsular antigens in sputum by incorporation of a carboxylated derivative of phenyl boronic acid.

Counter-current immunoelectrophoresis (CIEP) is now a well-recognised technique for the detection of pneumococcal antigens in body fluids. Much has been reported on its use in pneumococcal chest infections, but reports vary as to its ability to detect all pneumococcal types. Pneumococcal capsular types 7 and 14 could not be detected by Kenny et al. (1972) or Coonrod and Rytel (1973). El-Refaie ...
