What's this test for?

This test is ideal if you're experiencing unusual paleness, fatigue, or a bluish tint to your fingers, toes, ears, or nose, especially when exposed to cold temperatures. These symptoms can be signs of cold agglutinin syndrome, a condition where certain antibodies cause red blood cells to clump together when the body is cold. This test helps identify whether that immune reaction is happening in your blood.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained next to your value. If your result is elevated, simple next steps include staying warm, avoiding cold exposure, and retesting to see if levels change over time. A downloadable standard lab report is also available in your account, and you can track your results over time using the trends feature to see how your levels shift.

Who should consider this test?

This test is a good fit for anyone who notices their fingers, toes, or ears turning pale, blue, or numb in cold weather, or who has been told they may have symptoms linked to cold agglutinin syndrome. People who have had unexplained anemia along with cold sensitivity may also want to check this. It's a simple way to get more information before deciding on next steps.

What symptoms indicate I may need this test?

Common signs include fingers or toes turning white, blue, or purple in cold weather, along with numbness or pain in those areas. Some people also notice fatigue, dark urine, or a yellowish tint to the skin, which can happen when red blood cells break down. If cold weather consistently triggers these symptoms, this test can help clarify what's going on.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once ready, they'll be posted directly to your online account where you can view and download them. You'll get a notification so you know exactly when to check back.

How can I naturally support healthy circulation in cold weather?

Dressing in warm layers and keeping your hands, feet, and ears covered can reduce cold-triggered symptoms. Avoiding sudden temperature changes, like moving from a warm room to cold air, may also help. Staying active with light movement can improve blood flow, and some people find warm (not hot) drinks helpful during cold months.

What does a high cold hemagglutinins result mean?

A high result means your blood contains more cold-reacting antibodies than usual, which can cause red blood cells to clump together in cold temperatures. This clumping can lead to reduced blood flow to your extremities and, in some cases, contribute to anemia. If your result is high, avoiding cold exposure and retesting is a reasonable first step, and severe symptoms like significant pain or color changes should prompt urgent medical care.

What causes high cold hemagglutinins levels?

Elevated levels can be triggered by certain infections, like mycoplasma pneumonia or mononucleosis, or by underlying conditions affecting the immune system. In some cases, no clear cause is found and the levels are simply higher in some people than others. Retesting after an infection clears can help show whether the levels return to normal.

How often should I retest?

If your first result is elevated, retesting after a few weeks or months can help track whether your levels are rising, falling, or stable. If you're being monitored after an infection, retesting once symptoms resolve is a reasonable timeframe. Your trends page makes it easy to compare results side by side over time.

What should I do if my results are abnormal?

Start by reviewing the explanation provided with your result to understand what your specific value means. Simple steps like avoiding cold exposure and dressing warmly can help manage symptoms day to day. If you experience severe pain, significant color change in your fingers or toes, or signs of anemia like extreme fatigue, seek medical care right away.
