What to Do If You Test Positive on a Rapid Antigen Test
Understanding a Positive Antigen Test Result
A positive antigen test typically indicates a current infection with the SARS-CoV-2 virus, which causes COVID-19. These rapid tests are especially effective during the early stages of infection due to their fast turnaround time and ease of use. While not as sensitive as PCR tests, antigen tests can quickly identify infectious individuals, making them a valuable tool for early detection and containment.
Initial Steps After a Positive Result
If your at-home antigen test comes back positive, remain calm and take immediate steps to protect yourself and others. Even if you're asymptomatic or only experiencing mild symptoms, it's crucial to begin isolation right away. The Centers for Disease Control and Prevention (CDC) recommends isolating for at least five days from the date of your positive test or symptom onset.
Create a Safe Isolation Environment
Whenever possible, use a separate bedroom and bathroom to minimize contact with household members. Choose a well-ventilated room with access to fresh air—opening windows regularly can help reduce viral concentration indoors. Equip your space with essentials such as bottled water, healthy snacks, charging cables, and entertainment options like books or tablets to stay comfortable during isolation.
Essential Supplies for Home Recovery
Being prepared makes a big difference in managing your health effectively. Keep the following items on hand:
- Digital thermometer for daily temperature checks
- Pack of N95 or KN95 masks to wear when brief interactions are necessary
- Disinfectant wipes or sprays for cleaning high-touch surfaces
- Tissues, hand sanitizer, and trash bags with liners
- Hydration aids like electrolyte powders or sports drinks
Managing Common Symptoms Effectively
Most people experience mild to moderate symptoms that can be managed at home. Typical signs include fever, sore throat, dry cough, nasal congestion, fatigue, and occasionally gastrointestinal issues like nausea or vomiting. It's important to treat these based on your specific symptoms while avoiding unnecessary medication combinations.
Fever and Body Aches
For fevers above 38.5°C (101.3°F), over-the-counter medications such as ibuprofen (e.g., Advil or Motrin) or acetaminophen (Tylenol) can provide relief. Follow dosage instructions carefully and avoid exceeding the recommended amount within a 24-hour period. Stay hydrated by drinking plenty of fluids like water, herbal teas, or broths to support recovery.
Sore Throat and Cough Relief
To soothe a scratchy or painful throat, consider using lozenges, throat sprays, or traditional remedies known for their anti-inflammatory properties. Products like Lianhua Qingwen Capsules or Shufeng Jiedu Capsules may be used under medical guidance, particularly in integrative care approaches. Gargling warm salt water several times a day can also reduce discomfort naturally.
Medication Safety and Best Practices
Always read labels carefully before taking any medication. Many cold and flu products contain overlapping ingredients, increasing the risk of accidental overdose. Avoid combining multiple drugs with similar active components, such as acetaminophen, which is present in many formulations. When in doubt, consult a healthcare provider via telemedicine or pharmacist advice.
Preventing Transmission Within the Household
If you must leave your isolation area—for example, to use a shared bathroom—wear a high-quality mask and do so only when others are not present. Clean all touched surfaces immediately afterward, including doorknobs, faucets, and light switches. Encourage other household members to test regularly and monitor for symptoms.
When to Seek Medical Attention
While most cases resolve without complications, watch for warning signs that may indicate a more serious condition. These include difficulty breathing, persistent chest pain, confusion, bluish lips or face, or extreme fatigue. Individuals who are elderly, pregnant, or have underlying health conditions should contact their doctor promptly after testing positive, even if symptoms are mild.
Returning to Normal Activities Safely
After completing your isolation period, continue wearing a mask around others for an additional five days, especially in crowded or poorly ventilated spaces. Resume physical activity gradually and listen to your body. Full recovery may take time, and some people experience lingering symptoms—a condition sometimes referred to as "long COVID."
By following evidence-based guidelines and prioritizing self-care, you can navigate a positive antigen test result safely and responsibly, protecting both your health and the well-being of your community.
