As a preventive measure, valid information concerning the development of antibodies is being collected for assessing the progress towards herd immunity of COVID-19. Aim: To assess the level of Anti-SARS-CoV-2 IgG before and after vaccination by two doses of ChAdOx1 nCoV 19 vaccine in a rural Medical College of West Bengal. Materials and Methods: The present interventional cohort study was conducted in a rural Medical College and Hospital, West Bengal, India, from February 2021 to August 2021. Total 248 willing subjects were included for this interventional study from the same socio-economic and geographical distribution depending upon a vaccine population of a rural Medical College of West Bengal. To measure the anti-SARS-CoV-2 IgG antibody authors used Indian Council of Medical Research-National Institute of Virology (ICMRNIV) certified Anti-SARS-CoV-2 human IgG ELISA COVID KAVACH MERILISA kit and approved protocol by the ICMR. Results: The median age of study population was 39 years (range 25-64) with 97 (39.1%) females and 151 (60.9%) males. It was found that antibody response induced by two doses of vaccination was significantly high (t-value: 28.421, p<0.001) in the vaccinated population. Conclusion: Thus, present study suggests that vaccination may be critical to develop anti-SARS-CoV-2 IgG antibody. This would lead to a better understanding of the immunisation program and prevention of severe disease and deaths due to COVID-19.","PeriodicalId":31115,"journal":{"name":"National Journal of Laboratory Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71270942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elevated Low Density Lipoprotein cholesterol (LDL-c) is an important modifiable risk factor of atherosclerotic CVD. The LDL-c lowering strategy is a known recommendation for the prevention and treatment of CVD. The gold standard method of LDL-c estimation is β-quantification by ultra centrifugation. Other methods include Direct LDL-c measurement (D-LDL-c) using enzymatic assay which is tedious, time consuming and expensive. Hence, calculated method using Friedewald’s equation (F-LDL-c) is routinely used in clinical laboratories in India. Aim: To compare LDL-c values as estimated by direct enzymatic method with LDL-c values obtained by Friedewald’s equation and Novel’s equation, and, also to assess the effects of LDL-c values obtained by both the methods towards the risk stratification of CVD. Materials and Methods: A cross-sectional study, was conducted in the Central Diagnostic Laboratory of Mandya Institute of Medical Sciences, Mandya, Karnataka, India, for a duration of three months from July to September 2020, where, 600 subjects, aged 20-75 years, visiting for routine lipid profile estimation were included. LDL-c was estimated by direct enzymatic method (D-LDL-c) and calculated methods using Friedewald’s {F-LDL-c=TC-HDL-c- (TG/5)} and Novel’s equation {N-LDL-c=TC-HDL-c-(TG/Adjustable factor)}. Values obtained by calculated methods were compared with D-LDL-c values. The LDL-c values obtained were compared at different ranges of Total Cholesterol (TC), Triglycerides (TG) and High-Density Lipoprotein cholesterol (HDL-c). The association between direct and calculated LDL-c values were analysed by Pearson’s correlation. Receiver Operator Characteristic Curve (ROC) analysis was done to predict the better diagnostic method among the calculated methods of LDL-c. Results: The mean±SD of D-LDL-c (115.68±36.94 mg/dL) was high compared to F-LDL-c (106.95±33.48 mg/dL) and N-LDL-c (110.78±32.58 mg/dL). The mean difference between D-LDL-c and N-LDL-c (4.9±4.36 mg/dL) was low compared to F-LDL-c (8.75±3.46 mg/dL). Significant positive correlation was observed between D-LDL-c vs F-LDL-c (r=0.96; p=<0.001) and D-LDL-c vs N-LDLc (r=0.97; p=<0.001). The ROC showed maximum AUC value for N-LDL-c than F-LDL-c at a cut-off value of 100 mg/dL. LDL-c as estimated by Novel’s and Friedewald’s equation led to approximately 5% and 10% less patients being subjects for lipid lowering therapy respectively as compared to D-LDL-c. Conclusion: In conclusion, the use of Novel’s equation for LDL-c estimation instead of Friedewald’s equation could be associated with the small net increase in lipid lowering agent eligible population for primary prevention of atherosclerotic CVD. Replacement of Friedewald’s equation by Novel’s equation would enable for the improved accuracy of LDL-c estimation especially at higher levels of TC, TG and lower levels of HDL-c.","PeriodicalId":31115,"journal":{"name":"National Journal of Laboratory Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71270978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Delayed diagnosis and treatment can cause irreversible damage to the developing brain. The occurrence of cognitive dysfunction due to CH has reduced significantly in countries where Newborn Screening (NBS) is routinely practiced. Cord blood screening is considered to be an effective method to diagnose congenital hypothyroidism. Aim: To establish reference interval for thyroxine (T3 and T4) and Thyroid Stimulating Hormone (TSH) in cord blood Medical College, Thrissur. Materials and Methods: In the present cross-sectional observational hospital based study, the cord blood samples from 252 deliveries collected over a period of three months from May 2011 at in Government Medical College, Thrissur, Kerala, India. A 5 mL of cord blood samples were collected in a plain non vacuum tube with clot activator from umbilical cord incised 15-20 cm at the time of birth. T3, T4 and TSH was estimated by Enzyme Linked Immuno-sorbent Assay (ELISA) using kits of ELISA reader and Washer. Normality check done by visual inspection of histogram, Q-Q plot, box plot and Kolmogorov-Smirnov test. Results: In total of 153 cord blood samples considered, and final analysis was done on 151 samples (69 males and 82 females) after excluding the samples of babies delivered by Lower Segment Cesarean Section (LSCS). The gestational age was mean 38.48 weeks and mean age of mothers was 24.22 years. More than 90% of the values for TSH is less than 12 mIU/mL and 90% of T4 values is less than 20 µg/dL. Reference interval determined by non parametric ascending rank order. Reference interval established is 0.63-17.033 mIU/L and 9.45-27.173 for TSH and T4 respectively, lower than those reported from studies in other parts of India. The mean value of TSH was 5.084 mIU/L and 87.5% of babies are having TSH values <10 mIU/L.

Shortage of blood may be due to low donation rate, inadequate storage, improper transportation and wastage at ward side. Wastage of blood can have a negative impact on blood transfusion services. Aim: To determine the rates of wastage of blood and blood components units at the ward side and identify the various reasons for wastage and explain the strategies to reduce the wastage rate. Materials and Methods: This retrospective study was conducted in the Department of Transfusion Medicine, Sri Venkateswara Institute of Medical Sciences, Tirupati, Andhra Pradesh, India from January 2018 to December 2020. The data was collected from the blood centre record. All blood and blood components issued during the study period were included in the study. The number, type and blood group of blood and blood components issued, the number of blood units wasted after issue, and the reason for wastage was collected. The collected data were entered in Microsoft excel and analysed using Statistical Package for the Social Science (SPSS) version 21.0. Descriptive statistics were performed as necessary. Results: During the study period, a total of 69198 units of blood and blood components were issued to different wards and operation theatres in the hospital.
