What usually happens next

Not drinking enough before the test is the most common reason, and sodium is often at the high end too.

Diarrhoea and some kidney conditions raise chloride while lowering bicarbonate, so the bicarbonate is the other number to read.

What a high chloride usually means, and its common causes

When a chloride can read wrong

Chloride follows water and sodium: being dehydrated raises it, and IV saline raises it more. Some labs' ranges run to 107 or 110, so read it against the range on your report.
