  • occurrence
  • Biological samples have long been used in multiple laboratory investigations, and this procedure has been an issue of concern, as the samples are submitted to repeated freeze-thaw cycles, which may affect the results of a particular immunodiagnostic assay, due to the occurrence of physical damage to the antibody of interest.

  • substantial
  • There is a concern that these agents may irritate the body and cause biologically positive tests even in the absence of a more substantial illness, but there is some doubt about how frequently this occurs with NSAID medication. (wikipedia.org)
  • severity
  • The severity of the reaction whilst under anaesthesia is due to the fact that the anaesthetist is only made aware of the allergy when it is severe enough to compromise the cardiovascular system and the respiratory system. (wikipedia.org)
  • immune
  • This is done weeks after the initial reaction to allow the immune system to reset itself. (wikipedia.org)
  • It was first proposed by B. Magnusson and Albert Kligman in 1969 and described in their 1970 book Allergic Contact Dermatitis in the Guinea Pig The test animals are exposed intradermally to the test material, along with an adjuvant to enhance the immune reaction of the guinea pig.

  • prognosis
  • At the surgery's conclusion, the electrical stimulation penile plethysmograph result is a prognosis which helps to manage the erectile function outcomes earlier than the many months required for recovery. (wikipedia.org)
  • Variability
  • Our hypothesis is that the intervention group will have less variability as measured by mean deviation between exams and greater reliability as measured by the standard unreliability indexes of false positive rate, false negative rate, and fixation losses. (clinicaltrials.gov)
  • researchers
  • Since publication of these findings, there has been a great deal of interest from researchers in countries where ME/CFS is recognised and a number of research groups have attempted (or are still attempting) to confirm the positive findings. (meassociation.org.uk)
  • blood
  • None of these six research groups to report negative findings - which in the case of the UK included Professor John Gow, Dr Jonathan Kerr and Dr Jonathan Stoye and used patient samples from physicians including Dr Abhijit Chaudhuri and Professor Peter Behan - have been able to find XMRV in blood samples from ME/CFS patients, or in the healthy controls. (meassociation.org.uk)
  • The stool guaiac test involves fasting from iron supplements, red meat (the blood it contains can turn the test positive), certain vegetables (which contain a chemical with peroxidase properties that can turn the test positive), and vitamin C and citrus fruits (which can turn the test falsely negative) for a period of time before the test. (wikipedia.org)
  • Heme, a component of hemoglobin found in blood, catalyzes this reaction, giving a result in about two seconds. (wikipedia.org)
  • With venoplasty the physician feels with his own hands and sees with his own eyes immediate results: the restoration of blood flow. (blogspot.com)
  • Be aware that use of toilet bowl cleansers or the presence of blood derived from urine or a woman's menstrual period may alter results. (labtestsonline.org)
  • The World Health Organization estimated that, as of 2000[update], inadequate blood screening had resulted in 1 million new HIV infections worldwide. (wikipedia.org)
  • common
  • This is particularly common if the recommended dietary preparation is not followed, as the heme in red meat or the peroxidase or catalase activity in vegetables, especially if uncooked, can cause analytical false positives. (wikipedia.org)
  • patients
  • Results- Protein Z plasma levels were significantly lower in patients (mean 1.47 mg/L) than in controls (mean 1.93 mg/L) ( P =0.02). (ahajournals.org)
  • 7-9 With respect to arterial occlusive events occurring in SNS, protein Z status of patients with aPL-negative SNS seemed an interesting and yet unexplored perspective. (ahajournals.org)
  • Twenty-six patients with aPL-negative SNS (20 women, 6 men, mean age 48.9 years, range 36 to 64, mean body mass index 24.8) were enrolled in this study. (ahajournals.org)
  • 10 Given that nearly all aPL-positive patients with SNS receive long-term oral anticoagulation in our institution, 2 the study was restricted to aPL-negative SNS. (ahajournals.org)
  • color
  • A 3-10% solution of potassium hydroxide (KOH) gives a color change in some species of mushrooms: In Agaricus, some species such as A. xanthodermus turn yellow with KOH, many have no reaction, and A. subrutilescens turns green. (wikipedia.org)
  • The test is considered positive when a bright orange color forms where the lines cross. (wikipedia.org)
  • Therefore, a positive test result is one where there is a quick and intense blue color change of the film. (wikipedia.org)
  • Vitamin C can cause analytical false negatives due to its anti-oxidant properties inhibiting the color reaction. (wikipedia.org)
  • possible
  • In practice, it is possible to reanalyze the stored biological samples to confirm the results previously obtained or to perform further investigations. (jbpml.org.br)
  • Because it is not possible to control precisely the amount of tuberculin used in the tine test, a positive test should be verified using the Mantoux test. (wikipedia.org)
  • collapse
  • The standard model includes a resource base of double that of what they have calculated, but the book includes model runs where the assumed resources are infinite, but those model runs still result in overshoot and collapse from other factors. (wikipedia.org)
  • urine
  • The time taken for the appearance of the test results on the strip can vary from a few minutes after the test to 30 minutes after immersion of the strip in the urine (depending on the brand of product being used). (wikipedia.org)
  • Normal reference values are not provided for urine pH as the variation is too wide and results have to be considered in the context of the other quantifiable parameters. (wikipedia.org)
