A collaborative study to establish the 3rd WHO International Standard for hepatitis B virus for nucleic acid amplification techniques.
Nucleic acid amplification techniques (NAT) are routinely used for clinical diagnostics and monitoring hepatitis B virus (HBV) infections, and are implemented on a voluntary basis for blood screening. A collaborative study was performed to evaluate a replacement WHO International Standard for HBV for the standardization of NAT. Two lyophilised HBV candidates were evaluated by 16 laboratories wo...

Understanding its risk factors and strictly monitoring urine and serological markers of the infection could mitigate the undesirable effects of this disease. In this review, we investigate the clinical ...
متن کاملQuantitation of BK Virus DNA for Diagnosis of BK Virus-Associated Nephropathy in Renal Transplant Recipients
Quantitative measurement of BK virus DNA (Q-BKDNA) has been used for the early diagnosis and monitoring of BK virus-associated nephropathy (BKVAN). This study was designed to determine the BKDNA cutoff for the diagnosis of BKVAN. Between June 2005 and February 2007, 64 renal transplant recipients taken renal biopsies due to renal impairment submitted plasma and urine for Q-BKDNA. Eight BKVAN pa...
متن کاملVertical transmission of BK virus in pregnancy: A narrative review
Background: Primary infection with the BK virus occurs in the tonsils and is transmitted to other tissues and organs, especially the kidneys, by infecting monocytes. Infection with this virus is rarely associated with clinical disease but reactivating the virus in people who have a suppressed immune system can cause kidney or bladder damage. Due to the importance of activating the BK virus in s...
