The invention disclosed is a process for determining the cytoprotective activity of plasma that prevents the destruction of endothelial cells and forestalls the development of a number of diseases such as atherosclerosis, preeclampsia, edema, nephrotic syndrome, and stroke. The present invention includes a method of diagnosing a patient's proclivity to develop a disease having a correlation to a reduction in the concentration of pI 5.6 albumin in the plasma by determining a value indicative of the concentration of the pI 5.6 albumin that is not bound to VLDL ("free pI 5.6 albumin") in the patient's blood serum. The preferred embodiment of the process utilizes in vitro methods to obtain an indicator of the free pI 5.6 albumin instead of directly measuring the concentration of the free pI 5.6 albumin. The preferred method comprises the steps of:(a) providing a plasma sample containing free albumin, triglycerides, very low density lipoproteins, low density lipoproteins, and non-esterified fatty acids bound to the free albumin;(b) determining the concentration of the free albumin;(c) determining the concentration of the non-esterified fatty acids bound to the free albumin; and(d) calculating a value indicative of the toxicity preventing ability of the plasma by comparing the concentration of the free albumin to the concentration of the non-esterified fatty acids bound to the free albumin. The present process does not provide direct measurement of the cytoprotective activity of plasma, but rather, an empirical value which has clinical relevance in identifying patients with a high chance of developing diseases inhibited by pI 5.6 albumin. |
