Normal range: 80–100 fL (femtoliter) Mean corpuscular hemoglobin. Mean corpuscular hemoglobin (MCH) is the average amount of hemoglobin (Hb) per red blood cell ...
Hemoglobin H disease is a genetic disorder resulting in absent or impaired production of the α-globin protein, a normal component of the hemoglobin. The disease occurs when the α-globin gene expression is reduced to less than 30% of the normal expression. [2]
H/H or H&H: hemoglobin and hematocrit: HHS: Hyperosmolar hyperglycemic state: HHT: hereditary hemorrhagic telangiectisia HHV: human herpesvirus (including numerous subtypes such as HHV8) HI: homicidal ideation Hib: haemophilus influenzae B: HIDA: hepatobiliary iminodiacetic acid: HIDS: hyper-IgD (and periodic fever) syndrome HIE
They are never "hyperchromic". If more than the normal amount of hemoglobin is made, the cells get larger—they do not become darker. [2] It is calculated by dividing the total mass of hemoglobin by the number of red blood cells in a volume of blood. MCH=(Hb*10)/RBC (in millions) [3] A normal MCH value in humans is 27 to 33 picograms (pg)/cell ...
Both the Bombay and para-Bombay phenotypes are the result of point mutations in the FUT1 gene. At least one functioning copy of FUT1 needs to be present (H/H or H/h) for the H antigen to be produced on red blood cells. If both copies of FUT1 are inactive (h/h), the Bombay phenotype results.
A subgroup of H that is invariant under all inner automorphisms is called normal; also, an invariant subgroup. ∀φ ∈ Inn(G)： φ(H) ≤ H. Since Inn(G) ⊆ Aut(G) and a characteristic subgroup is invariant under all automorphisms, every characteristic subgroup is normal. However, not every normal subgroup is characteristic.
Normal values of hemoglobin in the 1st and 3rd trimesters of pregnant women must be at least 11 g/dL and at least 10.5 g/dL during the 2nd trimester. [96] Dehydration or hyperhydration can greatly influence measured hemoglobin levels. Albumin can indicate hydration status. If the concentration is below normal, this is called anemia.
During the early development of electrochemistry, researchers used the normal hydrogen electrode as their standard for zero potential. This was convenient because it could actually be constructed by "[immersing] a platinum electrode into a solution of 1 N strong acid and [bubbling] hydrogen gas through the solution at about 1 atm pressure".
