Brazil\u2019s participation in major national and international congresses throughout this year once again highlighted Controllab<\/a>\u2019s presence as a scientific reference in laboratory quality. At the 57th Brazilian Congress of Clinical Pathology\/Laboratory Medicine (CBPC\/ML)<\/a>, the 26th IFCC-EFLM EuroMedLab Congress of Clinical Chemistry and Laboratory Medicine<\/a>, and the ISQua\u2019s 41st International Conference<\/a>, the company presented studies that reveal consistent data applicable to the continuous improvement of laboratory services.<\/p>

The research covered topics ranging from molecular diagnostics to monitoring patient safety culture, demonstrating the role of Proficiency Testing<\/a> programs and Laboratory Indicators (Metricare)<\/a> in harmonizing practices and driving increasingly reliable results.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The study evaluated laboratories\u2019 ability to identify autoantibody patterns in ANA (Antinuclear Antibody) tests, based on national (BCA) and international (ICAP) consensus. Results showed good recognition of basic patterns (such as AC-0, with 95.2% accuracy), but difficulties with more complex nuclear patterns (AC-1, AC-2, and AC-29). The study reinforces the importance of continuous education to standardize laboratory practices, essential for diagnostic harmonization in autoimmune diseases.<\/p>

Two studies presented a 14-year performance overview of rapid tests for detecting antibodies to the human immunodeficiency virus (HIV) and the hepatitis C virus (HCV) in Brazil. Both showed high accuracy of the kits available on the market \u2014 with success rates above 98% in most cases \u2014 and a significant increase in the number of healthcare facilities participating. The results reflect the contribution of pre-market evaluation and post-market monitoring actions for rapid tests, ensuring ongoing quality and reliability of these assays over time.<\/p>

Another highlight among rapid tests was the study of the syphilis program, which showed significant growth in participant facilities \u2014 from 9 in 2010 to 113 in 2024 \u2014 and robust performance of the evaluated kits, with sensitivity and specificity above 98%. The data confirm the reliability of rapid tests and show how participation in the Proficiency Testing program ensures safety when releasing results.<\/p>

Two studies on HPV (Human Papillomavirus) compared the performance of molecular tests for detecting high-risk and low-risk oncogenic HPV. One study demonstrated that commercial kits (IVD) outperformed laboratory-developed tests (LDTs), especially in detecting high-risk HPV. In the other, although both test types (high and low risk) showed good results, there is room for improving accuracy in low-risk HPV detection. These findings support more assertive decisions when choosing tests for cervical cancer screening.<\/p>

The analysis of seven indicators harmonized by the IFCC showed stability in sigma metrics between 2018 and 2023, with highlight to sustained high performance in indicators such as \u201csample not received due to transport error\u201d (>7.0\u03c3). However, indicators such as \u201csample recollection\u201d and \u201cincorrect patient identification\u201d showed statistically significant deterioration, revealing critical areas for continuous improvement actions.<\/p>

A survey with more than 1,400 Brazilian clinical laboratory professionals revealed that managers perceive patient safety culture more positively than technicians, analysts, and administrative staff. This difference \u2014 mainly in aspects such as open communication, non-punitive response to errors, and leadership support \u2014 reinforces the need to engage all professional categories to ensure that the safety culture becomes fully established in institutions.<\/p>

Controllab\u2019s presence, with the presentation of scientific studies at these events, demonstrates the role of Proficiency Testing programs<\/strong> and Metricare (Laboratory Indicators) in generating data that guide the improvement of laboratory quality in Brazil and other countries.<\/p>

With programs accredited by ABNT NBR ISO\/IEC 17043<\/strong> and grounded in robust evidence, the studies strengthen the importance of continuous performance evaluation, harmonization of practices, and technical qualification of laboratory teams.<\/p>

These contributions encourage healthcare institutions of all sizes to promote analytical excellence and patient safety, reinforcing Controllab\u2019s commitment to applied science and the continuous development of laboratory medicine.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
