Fiber stimulates bowel movements by pushing food through your intestines. The most effective way to prevent constipation is to drink plenty of fluids and consume fiber foods that make you poop. Consuming 30g of fiber daily can help you maintain regular bowel movements. Seeds, like flaxseeds and sunflower seeds can also help you poop.
Methods for hemoglobinometry can be grouped into 4 main classes depending on the basic technique employed with variants within each class: 1. Colorimetric Methods. 2. Gasometric Methods. 3. Specific Gravity Methods. 4. Chemical Methods. The method of choice for hemoglobin determination is the cyanmethemoglobin method (This is a type of colorimetric method). The principle of this method is that when blood is mixed with a solution containing potassium ferricyanide and potassium cyanide, the potassium ferricyanide oxidizes iron to form methemoglobin.
Hemoglobin is usually measured as a part of the routine complete blood count (CBC) test from a blood sample. Several methods exist for measuring hemoglobin, most of which are done currently by automated machines designed to perform different tests on blood. Within the machine, the red blood cells are broken down to get the hemoglobin into a solution. The free hemoglobin is exposed to a chemical containing cyanide that binds tightly with the hemoglobin molecule to form cyanomethemoglobin. By shining a light through the solution and measuring how much light is absorbed (specifically at a wavelength of 540 nanometers), the amount of hemoglobin can be determined.
