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.
Urine osmolality is an index of the concentration of osmotically active particles, particularly chloride, sodium, urea, and potassium; glucose can also add significantly to the osmolality when it is abundant in urine. In a healthy state, the specific gravity of the urine corresponds to the urine osmolality. An evaluation of the osmolality, either routinely or under artificial conditions, indicates the kidneyâs ability to maintain tonicity and water balance of the extracellular fluid.
