What the Sedimentation Rate Really Says

·

If you’ve ever had a blood test and wondered what your ESR results mean, you’re not alone. The ESR, or erythrocyte sedimentation rate, is a common test used to check for inflammation in your body. But while it’s a useful tool, it doesn’t always paint the complete picture of your health. Let’s dive into what ESR is, what it can tell us, and why tracking it over time is so important.

What Is ESR?

ESR stands for erythrocyte sedimentation rate. It’s an inflammation marker that measures how quickly your red blood cells settle at the bottom of a test tube over an hour. The faster they settle, the higher your sedimentation rate, which typically indicates more inflammation in your body.

Seronegative Autoimmune Disease and Abnormal Test Results

·

Today is a question grab bag – we tackle your questions about seronegative disease and handling abnormal autoantibody results.

What is a Sero-Negative Autoimmune Disease?

First off, let’s talk about what “sero-negative” means. “Sero-” refers to blood, and “negative” means that when we run auto-antibody blood tests, they come back negative. So, a sero-negative autoimmune disease is one where these specific blood tests don’t pick up the antibodies we typically look for.

Deciphering the Rheumatoid Factor: More Than Just a Blood Test

·

Understanding the Rheumatoid Factor (RF) and its relationship with Rheumatoid Arthritis (RA) isn’t as easy as the names imply. You might think that a positive RF test result spells out RA without a doubt, but as with most things autoimmune, it’s not that simple.

The Rheumatoid Factor autoantibody

The Rheumatoid Factor is an autoantibody, which means it’s a protein produced by our immune system that mistakenly attacks our own tissues. Our immune system is constantly producing autoantibodies, however we also have a built-in regulatory system that finds these autoantibodies and destroys them – making sure they don’t cause trouble. When an autoimmune condition, like Rheumatoid Arthritis develops, it’s because our regulatory system is faltering and isn’t doing a good job of getting rid of autoantibodies and other autoimmune factors.

The Anti-CCP Test: A Breakthrough in Rheumatoid Arthritis Diagnosis

·

Let’s explore how this simple blood test has revolutionized the early detection of rheumatoid arthritis (RA), offering new hope and insights for patients and practitioners alike.

Understanding the Anti-CCP Test

Let’s start with the basics. The anti-CCP test is a crucial diagnostic tool used in the evaluation of RA. But what exactly does it measure, and why is it so important? The test detects the presence of autoantibodies (antibodies that attack your own body) against a class of proteins that have undergone citrullination. Citrullination is a process in which the amino acid arginine is converted into citrulline, one of many ways our body is able to produce this vital amino acid.

What does your “ANA Pattern” mean?

Navigating your ANA Test

Did you ever get an ANA test and feel confused by the results? You’re not alone! Many people feel puzzled when they hear about ANA patterns and what they mean for conditions like lupus. Our new video on YouTube is here to help you understand!

Understanding ANA Patterns

The ANA test checks for autoimmune conditions, but it’s not always easy to understand the results. A positive result doesn’t always mean you have a problem, and a negative result doesn’t always mean you’re okay. We need to look at other things too, like how you’re feeling and your medical history.
