What's this test for?

This test is ideal if you're already diagnosed with cryoglobulinemia and need to track how your cryoglobulin levels are changing over time. It's also useful if you're experiencing symptoms like joint pain, skin rashes, numbness, or circulation problems in cold weather that your prior testing has linked to cryoglobulins. This test is not meant to diagnose the condition for the first time — it's for monitoring a condition that's already been identified.

How should I prepare for this test?

How can you naturally support healthy circulation if you have cryoglobulinemia? Staying warm and avoiding sudden cold exposure can help reduce symptom flare-ups, since cryoglobulins can clump together in cold temperatures. Staying well hydrated and managing inflammation through a balanced diet rich in fruits, vegetables, and omega-3 fatty acids may also help support your circulation. Gentle regular movement can improve blood flow, but always ease into any new activity, especially if you have joint or nerve symptoms.

What's included in this test?

This test measures the percentage of your blood sample that separates out as cryocrit when chilled — this includes cryoglobulins, fibrin, or a mix of both. It's a follow-up measurement rather than a diagnostic panel, so it focuses specifically on tracking the quantity of these cold-sensitive proteins rather than identifying what type they are.

What happens after I get my results?

Your cryocrit percentage will show up in your account along with an explanation of what a normal range looks like so you can see where you fall. If your level has gone up, next steps often include reviewing your cold exposure habits and any known triggers, and possibly repeating the test at a schedule that matches how your levels have moved before. If your result is very high or paired with worsening symptoms like skin sores or severe joint pain, seek medical care right away. You can download a standard lab report from your account anytime, and the trends feature lets you compare this result with past ones to see your pattern over time.

When will I get my results?

Results for this test are typically ready within about 7 days of your blood draw. Because the cryocrit measurement requires the sample to be kept warm during collection and chilled slowly in the lab to separate out the cryoglobulins, the process takes a bit longer than routine bloodwork.

Who should consider this test?

This test is best for people who already have a confirmed cryoglobulin-related condition and are working to track it over time. It's commonly used by people with autoimmune conditions, certain chronic infections, or blood disorders known to cause cryoglobulins. If you've never been tested for cryoglobulins before, a screening test is usually the better starting point.

What symptoms indicate I may need this test?

If you already have a history of cryoglobulins and notice new or worsening joint pain, skin rashes or purple spots, numbness or tingling in your fingers and toes, or symptoms that flare up in cold weather, this test can help track whether your levels have changed. Fatigue and unexplained bruising can also be worth monitoring. These symptoms alone don't confirm cryoglobulinemia, but if you've already been diagnosed, tracking them alongside your cryocrit level can be helpful.

What does high cryocrit mean?

A higher cryocrit percentage generally means there's a larger amount of cryoglobulins or fibrin in your blood sample, which can correlate with more active symptoms like joint pain, skin changes, or circulation issues in cold weather. It doesn't tell you exactly what type of cryoglobulin is present, just how much cold-precipitating material showed up. A rising trend over multiple tests is often more meaningful than a single high reading.

How often should I retest?

Retesting frequency really depends on how active your condition is and how your levels have behaved in the past. Some people retest every few months to track stability, while others test more often during a symptom flare. Using the trends feature to log each result can help you and your results reviewer spot patterns and decide on a reasonable retest schedule.

What should I do if my results are abnormal?

If your cryocrit level is higher than your usual baseline, start by reviewing any recent cold exposure, infections, or lifestyle changes that might explain the shift. Keep track of any new or worsening symptoms like skin rashes, joint pain, or numbness, since these can help put the number in context. If you notice severe symptoms such as skin ulcers, intense pain, or signs of poor circulation, seek medical care promptly rather than waiting for your next scheduled test.
