Despite their familiarity, spreadsheets obscure analytical logic, encourage manual data manipulation, and lack durable records of analytical steps, limiting transparency, auditability, and reproducibility. These limitations present specific challenges in clinical laboratory settings subject to regulatory oversight. Script-based data analysis offers a practical alternative by encoding analytical workflows as explicit, ordered, and reusable operations. This review outlines the structural limitations of spreadsheet-centered analysis, illustrates how these constraints contribute to analytical error, and introduces script-based analysis using R as a reproducible framework suited to laboratory hematology. Practical applications are highlighted across method comparison, reference interval estimation, quality control, flow cytometry, and operational monitoring. The discussion also includes the importance of complementary technologies like integrated development environments, version control, and large language models. Adoption of reproducible, script-based analytical tools such as R represents a foundational step toward improving data integrity, analytical rigor, and readiness for advanced analytical techniques in laboratory hematology.</p>","PeriodicalId":14120,"journal":{"name":"International Journal of Laboratory Hematology","volume":"48 4","pages":"757-764"},"PeriodicalIF":2.2,"publicationDate":"2026-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijlh.70147","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147950498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efforts to improve LTA assessment of PFD with thrombocytopenia (e.g., Bernard Soulier syndrome) have led to validated, trustworthy diagnostic procedures. Commonly encountered PFD that manifest with abnormal aggregation responses to multiple agonists and/or DGD are now established to have significantly increased bleeding risks, emphasizing the need for diagnosis and treatment. Unraveling of the molecular pathogenesis of some specific PFD has provided important insights and simplified diagnosis. In the case of Quebec platelet disorder (QPD), the pathogenesis is a unique gain-of-function defect in fibrinolysis from a mutation that repositions a megakaryocyte-specific enhancer that normally upregulates <i>VCL</i> expression during megakaryopoiesis and “rewires” <i>PLAU</i>, increasing its expression &gt; 100-fold in megakaryocytes only.

Chronic iron overload is associated with either genetic disorders characterized by excessive iron accumulation (hereditary hemochromatosis), or is secondary to diseases of ineffective erythropoiesis and/or requiring regular blood transfusions (like thalassemia, sickle cell disease, myelodysplastic syndromes). Diagnosis is based on clinical suspicion, corroborated by laboratory findings such as elevated serum ferritin and transferrin saturation, along with imaging techniques (magnetic resonance imaging) which facilitate non-invasive assessment of iron levels in parenchymal organs. Elevated ferritin and transferrin saturation and exclusion of secondary causes should prompt genetic evaluation for hereditary disorders predisposing iron overload. Chronic systemic iron overload causes progressive tissue iron accumulation, leading to severe clinical implications, including myocardial dysfunction, liver cirrhosis, and increased risk of hepatocellular carcinoma. Monitoring includes evaluating iron overload indices (serum ferritin, transferrin saturation, liver and heart iron concentration) along with serum and urine indices of parenchymal organ damage at different timepoints regarding the type of disease, patient's age, severity and response to treatment, and aims in improving disease progression and preventing complications.

Pathology services, essential for accurate diagnosis and treatment, have merged to cope with these financial pressures. However, maintaining laboratory quality standards during economic downturns remains critical, as it directly affects patient outcomes, safety and satisfaction. This review explores evidence-based approaches to maintaining quality standards amid financial difficulties. Major challenges include hiring freezes, heavier workloads and an increased risk of burnout, which is associated with higher error rates and staff turnover. The Conservation of Resources theory helps explain burnout by highlighting the importance of organisational support. Strategies to mitigate burnout include policies for digital disconnection, the promotion of transformational leadership among junior managers and the fostering of supportive leadership at higher levels. Additional measures involve sustaining competencies through Entrustable Professional Activities, structured feedback, cross-training and Lean task prioritisation. Initiatives focused on staff well-being, centred on autonomy, psychological empowerment and happiness, are crucial for preserving morale and performance. Overall, these strategies demonstrate that quality can be maintained through structured, evidence-based interventions even during challenging times, thereby ensuring patient-focused care and organisational resilience.</p>","PeriodicalId":14120,"journal":{"name":"International Journal of Laboratory Hematology","volume":"48 4","pages":"732-736"},"PeriodicalIF":2.2,"publicationDate":"2026-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijlh.70117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147793250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
