Incidence of Variant Hemoglobin (Hb) and Increased Fetal Hb Concentrations and Their Effect on Hb A1c Measurement in a Korean Population

Incidence of variant hemoglobin (Hb) and increased fetal Hb concentrations and their effect on Hb A1c measurement in a Korean population.

To the Editor: Glycohemoglobin assays are important for evaluating long-term glycemic control in patients with diabetes (1 ). Ion-exchange HPLC is commonly used for measuring hemoglobin A1c (Hb A1c), but hemoglobin variants (Hb) or increased fetal Hb concentrations may affect the quantification of Hb A1c by HPLC. The presence of Hb or high Hb F concentrations can be recognized by the separate e...

A New Variant of Human Fetal Hemoglobin: Hb Froma.

Hemoglobin (Hb) Stanleyville II causes gross overestimation of the Hb A1c proportion in routine HPLC.

duction in neutrophils is induced by G-CSF, and NAP is released into the bloodstream, perhaps through leakage of ALP from damaged or dead neutrophils. Fossa et al. (9 ) reported leukocytosis and increased serum ALP in response to G-CSF treatment and suggested that increased serum ALP activity was related to release of the enzyme from the increased numbers of leukocytes. Neutrophils were reporte...

Practical Attacks on HB and HB+ Protocols

HB and HB+ are a shared secret-key authentication protocols designed for low-cost devices such as RFID tags. HB+ was proposed by Juels and Weis at Crypto 2005. The security of the protocols relies on the learning parity with noise (LPN) problem, which was proven to be NP-hard. The best known attack on LPN by Levieil and Fouque [13] requires subexponential number of samples and sub-exponential n...

Measurment of stable Glycosylated Hemoglobin (Hb A1) and Its unstable type (pre- Hb A1c) with the lon- exchange Chromatography in Diabetic patients

SUMMARY: At present, measurment of glycosylated hemoglobin, especially the stable fraction of hemoglobin (HbA1c) is one of the ways to control diabetes because this measurment can demonstrate total glycemia during last 1.2.3 months. Glycosylated hemoglobin is seen in 3 forms: Ala Alb A1c. Among these hemoglobin Alc is quantitively more than other 2 forms and its difference with other hemoglobi...
