Lab results returned with immunoglobulin m level of 224. my doctor suggested waiting and retesting in 6 months. is that safe?

Likely: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, an IgM level of 224 by itself is not a cause for concern. Do follow your doctor's advice. Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.

Missing data: You have not described why you had the test done, or what the IgM level was to specifically (general or germ). We like to give reasoned answers but that requires we don't guess about missing data. Waiting for what ? You are welcome to start over but please include the specifics in your post.
