Celebrating Heart Month
Heart disease is the No. 1 killer of women. During American Heart Month in February, Mark Twain Medical Center offers no-cost testing to help local women monitor their heart health.
Make time any weekday in February for a comprehensive lipid panel test. It can help identify chronic and new conditions like cholesterol numbers and other risk factors.
It's simple. To get your 2025 no-cost lipid panel test, bring your photo ID to the MTMC Laboratory Monday through Friday from 7 am to 1 pm. You must start fasting 12 hours prior to your visit for accurate results.
This program is made possible by funding from Soroptimist International of Calaveras County as part of their commitment to women's health.
