  • As many as 50% of positive blood culture results have been estimated to be falsely positive. (medscape.com)
  • This rate probably has decreased, but false-positive blood culture results remain a major diagnostic challenge. (medscape.com)
  • The system can analyze a positive blood culture sample in approximately five hours, which is faster than traditional testing techniques. (morningstar.com)
  • minor criteria are positive blood cultures or elevated inflammatory indices with no alternative source. (kcl.ac.uk)
  • Moreover, patients with higher blood CRP levels showed greater SBP prevalence compared to patients with lower levels, despite similar positive culture results. (frontiersin.org)
  • In 3 cases, intracellular gram negative diplococci were seen in smear, N. meningitidis was isolated from culture and both CIEP and latex agglutination for N. meningitidis were positive. (jpgmonline.com)
  • In 1 case, smear, culture and LAT were positive but CIEP was negative. (jpgmonline.com)
  • In 2 cases, though smear showed intracellular Gram negative diplococci, culture was negative for growth but CSF gave a positive latex agglutination test (CIEP was negative). (jpgmonline.com)
  • The PCR positivity increased significantly with increasing seropositivity titres by the standard tube agglutination test and showed 100% positivity in patients with positive blood cultures. (who.int)
  • We did Gram stains and cultures on exudates from open wounds and on aspirates if the wounds had demonstrable fluid collection. (who.int)
  • RESUME Afin de déterminer la microbiologie de l'infection de la plaie après une césarienne et d'évaluer l'utilisation de la coloration de Gram pour prévoir les résultats des cultures microbiologiques ultérieures, 1319 plaies chirurgicales ont fait l'objet d'un suivi. (who.int)
  • Nous avons procédé à une coloration de Gram et à des cultures sur des exsudats de plaies ouvertes et des échantillons prélevés par aspiration si la plaie avait une accumulation de fluides manifeste. (who.int)
  • False negative blood culture results due to inadequate volumes of blood can result in misdiagnosis, delay therapy, and put patients at heightened risk of morbidity and mortality from bacteremia. (cdc.gov)
  • To evaluate patients with fever of unknown origin or those with suspected bacteremia, the precision of blood culture tests is critical. (jmir.org)
  • The new ink can be fully absorbed into the meat product and is cheap to produce, so it could significantly reduce the cost of large-scale cultured meat production. (nanowerk.com)
  • There were significantly higher levels of IL-6 in ascites fluid compared to blood samples in all patients. (frontiersin.org)
  • In the future, if suitable plant extracts can be found to supply nutrients, that will further reduce the cost of cultured meat, making it more affordable," Professor Sun concludes. (nanowerk.com)
  • This course teaches all aspects of phlebotomy, with current coverage of equipment, safety procedures, arterial blood gases, point-of-care testing, and practical phlebotomy skills. (lsco.edu)
  • Failure to establish arterial access precludes continuous invasive monitoring of blood pressure and sampling of arterial blood gas, both of which are desirable in the management of ventilated neonates. (bmj.com)
  • Following careful assessment of various culture conditions, we describe here the robust continuous cultivation of the blood stages of P. cynomolgi lines derived from the Berok strain. (nature.com)
  • Our techniques allowed us to measure the inflammatory potential of an individual's lipids outside of the body and to correlate that with easily measured characteristics that could be used to help better understand a person's risk for vascular disease," Passerini said. (ucdavis.edu)
  • However, such screening strategies are precluded for P. vivax because of the limited availability of infected blood from patients, an obstacle that would be circumvented should in vitro-cultured P. cynomolgi be available. (nature.com)
  • La positivité de la PCR augmentait de façon significa- tive avec l'augmentation des taux de séropositivité d'après le test classique d'agglutination en tube et s'élevait à 100 % chez les patients dont les hémocultures étaient positives. (who.int)
