Esophageal pH monitoring is performed for 24 or 48 hours and at the end of recording, a patient's tracing is analyzed and the results are expressed using six standard components. Of these 6 parameters, a pH score called Composite pH Score or DeMeester Score has been calculated, which is a global measure of esophageal acid exposure. A Demeester ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Herpetic gingivostomatitis is an infection caused by the herpes simplex virus (HSV). The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.
False negative test results may occur if the test is performed late in the course of the illness or if the test sample is not appropriately acquired. [17] Testing people for HSV when they are asymptomatic is not recommended due to the high false-positivity rate. [18] A false positive test may cause relationship difficulties. [18]
An ELISA technique for CMV-specific IgM is available, but may give false-positive results unless steps are taken to remove rheumatoid factor or most of the IgG antibody before the serum sample is tested. Because CMV-specific IgM may be produced in low levels in reactivated CMV infection, its presence is not always indicative of primary infection.
Physiologically normal intracellular pH is most commonly between 7.0 and 7.4, though there is variability between tissues (e.g., mammalian skeletal muscle tends to have a pH i of 6.8–7.1). [4] [5] There is also pH variation across different organelles, which can span from around 4.5 to 8.0. [6] [7] pH i can be measured in a number of ...
According to a study in Ontario, of people between the ages of 15 and 16, 26.9% of men, 32% of non-pregnant women, and 55% of pregnant women tested positive for HSV-1 antibodies. Between the ages of 40 and 44, 54.7% of men, 88.7% of women, and 69.2% of pregnant women tested positive for HSV-1 antibodies.
The results above are consistent with those of previous studies that involved HSV-1 (and a number of other viruses), which also disseminates into the CNS through olfactory tissue. [ 36 ] Researchers also hypothesized that olfactory ensheathing cells (OECs), a group of specialized glial cells found in the nasal cavity, may have a role in HHV-6 ...
