JOURNAL OF CLINICAL TRANSFUSION AND LABORATORY MEDICINE. 2017 (5):  498-501.  DOI: 10.3969/j.issn.1671-2587.2017.05.026
Abstract ( 609 )   PDF(1670KB) ( 1014 )  
Objective To investigate the effect of chyle levels of plasma turbidity plate and degrees of plasma hemolysis shadeguide for reducing the unnecessary retirement of plasma due to objective incorrect assessment in the process of blood collection and supply. Methods Fifteen staffs were randomly grouped to compare the chyle and hemolysis samples in critical level at different light by chyle plasma turbidity plate and plasma hemolysis shadeguide in order to check the influence of the natural or artificial light. The chyle and hemolysis plasma discarding data were analyzed from 2012 to 2013. Results There was no difference between the natural light and the light of lamp(P>0.05)whereas a significant difference was seen between chyle levels of plasma turbidity plate and degrees of plasma hemolysis shadeguide(P<0.05). In the year of 2012,the rate of chyle plasma discarding was 0.46%,and that of hemolysis plasma discarding was 0.26%. In 2013,however,the rate of chyle plasma discarding was 0.41%,and that of hemolysis plasma discarding was 0.18%.The rates of both plasma discarding have been obviously reduced after using chyle levels of plasma turbidity plate and degrees of plasma hemolysis shadeguide (P≤0.01). Conclusion The chyle levels of plasma turbidity plate and degrees of plasma hemolysis shadeguide may effectively control the unnecessary retirement of chyle and hemolysis plasma,and can be used as a convenient and effective method to distinguish the chyle and hemolysis plasma in the process of blood collection and supply.

Abstract ( 634 )   PDF(781KB) ( 692 )  
Objective To analyze the results of blood virus screening by both nucleic acid test (NAT) and ELISA to evaluate the significance of NAT in improving blood safety. Methods We randomly collected 19 464 blood samples from volunteers between 2015 and 2016. The blood samples were detected by ELISA for screening of anti-HIV,anti-HCV and HBsAg,followed by PCR fluorescence detection for nucleic acids of HBV,HCV and HIV in the samples which had showed negative reactions in ELISA. The comparative results were evaluated for the efficiency and significance in laboratory diagnoses and blood safety ensurance. Result The positive rate of HBV was 16.0% by NAT compared with 11.0% by ELISA (P<0.05). HCV detected by NAT revealed a positivity of 1.8% ,which is obviously higher than 0.5% by ELISA (P<0.05). The positive rate of HIV,however,was 1.9% by NAT whereas 1.7% by ELISA,no significant difference was noted between the two methods (P>0.05). Conclusion Pre-examination of blood samples with ELISA followed by NAT verification is recommended for blood screening which may help avoid missing or misdetection of samples in ELISA and help improve sensitivity and accuracy in the safety of blood transfusion.

Abstract ( 585 )   PDF(815KB) ( 1707 )  
Objective To Use the fluorescence quantitative PCR (FQ-PCR) for confirming antibodies against hepatitis C surface antigen(anti-HCV)that had been tested by enzyme linked immunoassay(ELISA). Methods 1 348 patients who had experienced blood transfusion and operation were collected from April 2012 to March 2016.The patients were divided into three groups,group A included 240 samples with negative anti-HCV detected by ELISA (S/CO<0.3); group B covered 902 samples with anti-HCV on cutoff value (0.7≤S/CO<1); and group C included 206 samples with weak reaction of anti-HCV detected by ELISA. Results Among groups B and C,41(4.54%)and 172(83.49%) samples were found to have HCV RNA level>1 000 IU/ml rechecked by FQ-PCR. FQ-PCR demonstrated a high positive rate in the samples on the cutoff value tested by ELISA double reagents(P<0.05); while no difference was noted between the samples with weak reaction of HCV RNA when tested with ELISA and FQ-PCR(P>0.05). Conclusion The false negative and misdiagnosis rate of ELISA is high in the samples near HCV cutoff value and in weak reaction,suggesting that FQ-PCR is useful for early diagnose of HCV patients.
