Inappropriate Hemoglobin A_lc Level, Interference or Bonus?

Association between diabetic retinopathy and hemoglobin level

Background: Anemia may be considered to be an independent risk factor for the development of diabetic retinopathy (DR) in patients with renal failure. The purpose of this study was to investigate the association between blood hemoglobin level and retinopathy in diabetic patients with normal renal function tests.Methods: From 2009 to 2011, 1100 diabetic patients underwent retinal examination. Am...

Hemoglobin F level in different hemoglobin variants

BACKGROUND Fetal hemoglobin (HbF) levels in different hemoglobin variants in Osogbo, Nigeria, were estimated using two principal methods of estimation using existing information for HbF concentration and distribution of various hemoglobin variants in the area, as well as diagnosed cases of thalassemia. Two hundred and sixty samples collected from HbSS, HbSC, HbAA, HbAS, and HbAC subjects were a...

Hemoglobin interference from in vivo hemolysis.

Laboratory values for specimens from a case of intravascular hemolysis showed that hemoglobin was significantly increased and thus could interfere with the determination of other analytes. We studied this problem by adding increasing amounts of purified hemoglobin (to a maximum concentration of 19.3 mg/L) to aliquots of pooled serum samples. The hemoglobin significantly interfered with the dete...

Bonus or Not? Learn to Reward in Crowdsourcing

Recent work has shown that the quality of work produced in a crowdsourcing working session can be influenced by the presence of performancecontingent financial incentives, such as bonuses for exceptional performance, in the session. We take an algorithmic approach to decide when to offer bonuses in a working session to improve the overall utility that a requester derives from the session. Speci...
