@Fdprefect: it could be as you suggested BUT check her recent diet.

My wife got hyperkalemia when she ate potassium-rich foods almost exclusively for a few weeks straight and drank V8 juice. ER had her drink yucky stuff that binds excess potassium and then you excrete it. Her cardiologist spotted it in the pre-visit bloodwork as it can really screw you up if not caught. He's the one her sent her directly to ER, do not pass go, they'll collect the $2,000.

Being "encouraged" to damage your body sucks. Being "fired" for not wanting to be a walking failed experiment for many will not end well for employers. They may even learn from their severe error if/when key employees who got vexxed become major drags on their employer-paid health plans or become disabled(workmens comp until that runs out), or die. Maybe the vexxed will face higher premiums for both healthcare coverage and life insurance for THEIR mistake.

Count me in on donating non-vexxed blood when it becomes a premium-priced product.
