To explore the design and implementation of automatic verification rules using a laboratory information system (LIS) to optimize blood cell analysis, thereby improving laboratory efficiency and accuracy.
Methods
A total of 25 692 laboratory reports were collected and analyzed, including blood cell counts, classifications, and cell morphology indicators. Automatic verification rules encompassing patient information validation, sample information verification, critical value identification, and instrument alarm information validation were designed and implemented using the built-in scripting language of the LIS.
Results
The implementation of the automatic verification rules, which comprised 64 rules across five categories, processed 25 692 reports. Among these, 19 140 reports passed automatic verification, resulting in a pass rate of 74.50%. A total of 6552 reports failed automatic verification, triggering 11 986 rule interceptions. The automatic verification system reduced the median turnaround time (TAT) from 15 minutes to 3 minutes, decreased the error rate of reports from 0.082% (16/19 526) to 0.008% (2/25 692), and lowered patient dissatisfaction from 15.38% (10/65) to 1.19% (1/84).
Conclusions
The design and implementation of automatic verification rules effectively enhance laboratory efficiency and quality, significantly improving patient satisfaction. Future research should aim to further optimize these rules to address more complex clinical scenarios and explore advanced technologies to support the continued development of automated blood cell analysis.
To evaluate the analytical performance of lipid detection items using the Six Sigma model and to develop individualized internal quality control (IQC) strategies and precise improvement measures.
Methods
The WS/T 403-2024 Analytical Quality Standards for Common Clinical Chemistry Tests served as the quality goal for lipid testing. Accuracy was assessed using data from the first 2024 external quality assessment of lipid provided by the Shaanxi Provincial Clinical Laboratory Center, while precision was evaluated based on IQC data from our laboratory. The sigma metric for each lipid parameter was calculated based on these three indices and plotted on a standardized sigma performance chart. Furthermore, individualized IQC strategies and improvement measures were formulated using the Westgard Sigma Rules flowchart and by analyzing the quality goal index.
Results
The analytical performance of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and apolipoprotein A (Apo-A) was rated as "Good", while that of apolipoprotein B (Apo-B) achieved "World Class" level. The recommended IQC strategy for TC, TG, HDL-C, LDL-C, and Apo-A were the 13s/22s/R4s/41s multi-rule approach (N=4) with a batch length of 200 samples. For Apo-B, the recommended strategy was the 13s multi-rule (N=2) with a batch length of 1000 samples. Notably, precision deficiencies were observed in five lipid analytes, warranting prioritized improvement measures.
Conclusion
The Six Sigma model demonstrates significant utility in evaluating lipid analyte performance, designing IQC strategies, and implementing quality improvements, thereby enhancing laboratory testing capabilities.
To develop and evaluate the immune response levels following SARS-CoV-2 vaccination or infection, a neutralizing antibody detection method based on fluorescent immunochromatography was developed and subsequently subjected to preliminary performance assessment.
Methods
The fluorescent immunochromatographic assay employs a competitive format. The test strip is coated with fluorescent microspheres-labeled receptor-binding domain and immobilized angiotensin-converting enzyme 2 along with sheep anti-mouse antibodies. This configuration enables quantitative detection of SARS-CoV-2 neutralizing antibodies in serum or plasma through fluorescence signals.
Results
The method quantifies neutralizing antibodies for SARS-CoV-2 at two concentrations (906 IU/ml and 1865 IU/ml), with within-batch coefficients of variation of 10.16% and 8.20%, respectively. The between-batch coefficients of variation are 10.43% and 9.48%, respectively. This method exhibits no cross-reactivity with other antibodies, indicating robust specificity. Analytical sensitivity showed a limit of detection concentration is 125 IU/ml, with an optimal measurement range spanning 125-3600 IU/ml. The total concordance rate with the pseudovirus neutralization test (pVNT) method is 87%, with a positive concordance rate of 85% and a negative concordance rate of 100%. In addition, the Kappa coefficient was 0.54 (P<0.001), indicating that the chromatography method had moderate consistency with the pVNT results.
Conclusion
This rapid and accurate fluorescent immunochromatographic assay provides a reliable tool for evaluating vaccine efficacy and treatment outcomes in SARS-CoV-2 patients.
To characterize the genotype distribution and hematological profiles of thalassemia carriers among women of childbearing age in Yuhuan, Zhejiang Province, thereby providing a scientific basis for thalassemia screening and prevention.
Methods
From May 1, 2021 to February 28, 2022, routine blood tests were performed on women aged 15–49 years at Yuhuan Maternal and Child Health Hospital. Individuals with hemoglobin (Hb)<115 g/L and mean corpuscular volume (MCV)<82 fL, or Hb<115 g/L and mean corpuscular hemoglobin (MCH)<27 pg, were further subjected to thalassemia gene detection and high-resolution hemoglobin electrophoresis. The hematological results of patients with different genotype abnormalities were analyzed.
Results
A total of 2039 women of childbearing age were included. Among them, 318 subjects meeting the criteria of Hb<115 g/L with MCV<82 fL, or Hb<115 g/L with MCH<27 pg underwent thalassemia gene detection. A total of 64 thalassemia gene carriers were identified, with a detection rate of 20.13% (64/318). Among them, 53 cases carried α-thalassemia genes, predominantly SEA type and 3.7 type; 10 cases carried β-thalassemia genes, predominantly IVS-Ⅱ-654 point mutation; and 1 case carried α/β compound thalassemia gene, with the genotype of CS+IVS-Ⅱ-654.
Conclusions
The α-thalassemia genes in women of childbearing age in Yuhuan area are predominantly SEA type heterozygote (--/αα) and 3.7 type heterozygote (-α/αα), while the β-thalassemia gene is predominantly IVS-Ⅱ-654. Characteristic analysis based on the hematological results of patients with genetic abnormalities can provide a reference for thalassemia screening in this region.
To determine the carrier rate of spinal muscular atrophy (SMA) among women of reproductive age in the Shaoguan, Guangdong Province, and to provide prenatal diagnosis for couples where both partners are identified carriers, aiming to prevent the birth of SMA-affected infants.
Methods
A total of 2646 pregnant women were screened using fluorescent quantitative PCR technology to detect the copy number of exons 7 and 8 (E7, E8) of the survival motor neuron gene 1 (SMN1). Prenatal diagnosis was conducted for high-risk couples who were both SMA carriers, and the fetal genotype results were verified using multiplex ligation-dependent probe amplification (MLPA).
Results
Among the 2646 pregnant women, 54 SMA carriers were identified, yielding a carrier rate of 2.04% (54/2646). The carrier genotypes were categorized as follows: 41 cases had concurrent heterozygous deletions of SMN1 gene E7 and E8, 1 case had an isolated heterozygous E7 deletion, and 12 cases had an isolated heterozygous E8 deletion. Prenatal diagnosis was performed for two couples who were both partners carried a heterozygous SMN1-E7 deletion. The results identified one fetus with a heterozygous deletion of SMN1-E7 and E8 and one fetus with a normal genotype. These findings were consistent with the MLPA verification.
Conclusions
The carrier rate of SMA mutations in the pregnant population is relatively high in Shaoguan region of Guangdong. It is necessary to conduct SMA carrier screening among pregnant women and to perform invasive prenatal genetic diagnosis for high-risk fetuses whose parents are both SMA carriers. This approach is of great significance for effectively preventing the birth of SMA-affected infants and reducing the incidence of birth defects.
