Conversely, the shrinkage of the deficit and the emergence of the short-lived surplus in the second half of the 1990s caused the weighted-average maturity of the debt to increase sharply despite the Treasuryâs abandonment of the 30-year bond and commitment to issuing debt at shorter maturities.
Osmolality - blood test. Osmolality is a test that measures the concentration of all chemical particles found in the fluid part of blood. Osmolality can also be measured with a urine test. A blood sample is needed. Follow any instructions from your health care provider about not eating before the test.
The osmolality of a fluid is a measure of the number of particles in a solution. In a drink these particles will comprise of carbohydrate, electrolytes, sweeteners and preservatives. In blood plasma the particles will comprise of sodium, proteins and glucose. Blood has an osmolality of 280 to 330mOsm/kg. Drinks with an osmolality of 270 to 330mOsm/kg are said to be in balance with the bodyâs fluid and are called Isotonic. Hypotonic fluids have fewer particles than blood and Hypertonic have more particles than blood. Consuming fluids with a low osmolality, e.g. water, results in a fall in the blood plasma osmolality and reduces the drive to drink well before sufficient fluid has been consumed to replace losses. Which is most suitable?
