Catlab Reports Bulletin
The Catlab Reports Bulletin is published monthly. Until the publication of the Catlab website, it was mailed electronically to our clients. It consists of a monograph related with laboratory topics. Each month it addresses a different area of Catlab; the topics can be more specific (concrete diagnostic techniques) or deal with more generic aspects (Quality, Management, …).
GENETICS - Molecular markers in glioma
Glioma is the most common primary tumor among intracranial malignancies. There is a growing number of biomarkers in glioma in the field of research, but currently in routine three are used: Codeletion 1p / 19q; IDH 1/2 mutation; and Methylation of MGMT.
QUALITY - Surveys for emergency physicians
Within the 2016-2018 Customer Satisfaction Measurement Plan, Catlab carried out surveys of the emergency physicians of HUMT, FHSJDM and CST. The results of the 9 consensual questions of the survey are exposed, on the perception and the evaluation that the laboratory professionals have, and the conclusions and improvement actions that have been started from the Laboratory.
MICROBIOLOGY - Tuberculosis
Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis. In this bulletin, we will see how it is acquired, how it is diagnosed and how it is treated. The current frequency of the disease, and the tests available to the Laboratory to diagnose it.
MANAGEMENT - Catlab tenth anniversary
To commemorate the 10th anniversary of Catlab, on June 7 a successful scientific conference was held in Catlab with the title "Genetics: from the laboratory to clinical practice". In this "Catlab Informa" we review the trajectory of our Laboratory in these 10 years, its current organization, and how it has been consolidated as one of the largest laboratories.
URGENT CARE - Preeclampsia Markers
Preeclampsia is a hypertensive disorder of pregnancy, which causes an important maternal-fetal morbidity and mortality, which affects 2-8% of pregnancies. In recent years, numerous studies have attempted to determine markers of Predicting the risk of preeclampsia, identifying the women with greater risk, and creating strategies to reduce its prevalence. In Catlab we have started using the sFlt-1 / PlGF ratio as a marker of preeclampsia.
BIOCHEMISTRY - Vitamin D: Update
Recently, the reference values that appear in our report laboratory of Vitamin D have been modified. Currently, there are different methods for measuring them, and the reference values depend on the population studied. They vary with sex, age, seasonal period, geographical latitude, diet, body mass index, ethnic group ... With this great variability, we have decided to update the reference values following the recommendations of the "Protocol d'indicacions per la mesura de vitamina D" approved by the ICS.
MICROBIOLOGY - New swabs
The first step of the microbiological diagnosis begins with obtaining the clinical sample; it must be representative of the infectious process that is wanted to diagnose. All the information that the microbiology laboratory can generate depends almost completely on the sample that is sent. Therefore, it is essential that the obtention procedure, the quantity sent, the type of transport and the appropriate speed of delivery. The consequences of a poorly collected and / or badly sent sample may result in the failure to isolate the etiologic agent of the infection.
GENETICS - TCR Clonality
The T cell receptor (TCR) is a membrane receptor, present in mature T lymphocytes (LT), constituted by two different transmembrane polypeptide chains. The αβ T lymphocytes constitute around 95% of the total circulating T lymphocytes in peripheral blood, and are the best characterized in terms of their biology and functions. Its TCR is a heterodimer consisting of an α and a β chain. The genes that code for each of the chains of the TCR, are formed by a set of different segments that, during the maturation of the LT, unite in a random and irreversible way, through a directed process of somatic recombination of the DNA. The study of the gene rearrangements of the genes encoding the TCR is a marker of clonality and, therefore, of malignancy, ideal in the diagnosis and monitoring of lineage PFS.
HEMATOLOGY - Graphic reports in the studies of Hemoglobinopathies
Since this month of January, can be seen in the studies of hemoglobinopathies
(hemoglobins A2 and F, electrophoresis), in addition to the percentage of variant hemoglobin and the numerical result, a graphic report with the chromatograms by HPLC (high efficiency liquid chromatography), and the scanned images of the alkaline electrophoresis plate if it has been carried out this technique. The objective is to provide a more detailed result, and facilitate its interpretation.
QUALITY - Customer satisfaction measure in Hospitals
During the years 2016-2017, in Catlab, surveys were carried out to the different Hospital assistance groups of HUMT, FHSJDM and CST. The 8 consensual questions of the survey are related on the perception and the evaluation that the professionals of the Hospitals of the laboratory have.
