BACKGROUND This study compared the estimated costs and times required for ABO/Rh(D) typing and unexpected antibody screening using an automated system and manual methods. METHODS The total cost included direct and labor costs. Labor costs were calculated on the basis of the average operator salaries and unit values (minutes), which was the hands-on time required to test one sample. To estimat...

ABO and Rh (D) groups of 6403 blood samples were assessed on an 8/9-channel autoanalyser in the Serology Department of the London Hospital; the results were independently checked at the Regional Blood Transfusion Centre, Brentwood, using the routine methods for grouping donor blood. Results of this comparative study are given and instances are described in which anomalous results or incorrect g...

BACKGROUND AND OBJECTIVES Serologic agglutination tests have the disadvantage of lack of an objective endpoint that can be easily read and quantitated. We have developed a new method for ABO and Rh typing based on producing a red blood cell (RBC) monolayer on microplates and the mixed hemagglutination reaction. MATERIALS AND METHODS We have employed a new red cell fixation buffer to prepare t...

Cases were selected from the Skin Out-patients Department and Leprosy Clinic of S.S. Hospital, Banaras Hindu University and the Leprosy Clinic at Chowka Ghat, Varanasi. Patients belonging to any other province or country were excluded. Blood was grouped by the slide method described by Stratton and Renton (1958). The control material consisted of data on 2583 recipients of blood at the hospital...

The importance of determination of ABO Blood Groups in antenatal patients is considered, particularly in the context of the diagnosis of ABO mediated haemolytic disease of the newborn and blood transfusion during pregnancy and delivery. It is concluded that the investigation is of little benefit to either patient or doctor, and that it should be abandoned as part of routine antenatal procedures.

The present study is based on a sample of 587 mothers and 1656 pregnancies. The results show that Opositive and B-positive mothers are more successful in reproduction and indicate low percentage of prenatal loss (stillbirths+abortions) than mothers from other ABO groups. Favourable age of marriage for O-positive and B-positive mothers is suggested between 15-22 years and 23-30 years respectivel...

The ABO blood group and secretor status of 1,000 alcoholic patients has been determined. The patients were drawn from large alcoholic units in the London area together with several small units, including rehabilitation centres, nd 127 were from Aberdeen.The findings have been compared with appropriate controls which take into account the ethnic origin of the patients in the series. A striking d...

The present study reports the distribution of ABO blood groups and Rh (D) factor among the Sunni Muslim population of Jaunpur (Uttar Pradesh), north India. The percentage of A (30.5%), B (30%), O (28%) and AB (11.5%) groups and the frequencies of O, A and B alleles were found to be (0.5270, 0.2381, and 0.235, respectively) were similar to previously reported data on ABO system from Jaunpur. The...
