This depends on the reason why your doctor asked you not to disclose the reason for donating blood, and if this blood will be used in patients after you donate it or if it will be discarded. A blood with elevated hematocrit is usually more viscous than usual and this may be a contraindication to its use in patients who need blood, especially if these patients have blood diseases. Please discuss this with your treating physician and raise your concerns before donating blood.

Annual Checkup
It is recommended that all individuals see a Family Doctor for a full medical examination annually. Adults should get their blood pressure checked (US Preventive Task Force), a flu vaccine (CDC) and more each year.
The American Dental Association recommends dental cleanings for adults at least twice annually. Some stains can only be removed by a professional cleaning.
It’s recommended by the American Academy of Ophthalmology that every adult between the ages of 18 and 80 does an eye examination at least once every two years.
It's recommended by the American Cancer Association that every adult between the age of 20 and 80 does an annual skin screening by a licensed dermatologist.
