Antinuclear antibodies are associated with rheumatic diseases including Systemic Lupus Erythematous (SLE), mixed connective tissue disease, Sjogren's syndrome, scleroderma, polymyositis, CREST syndrome, and neurologic SLE. 

Reflex Information: If ANA Screen, IFA is positive, then ANA Titer and Pattern will be performed at an additional charge.


Increased CRP levels are found in inflammatory conditions including: bacterial infection, rheumatic fever, active arthritis, myocardial infarction, malignancies and in the post-operative state. This test cannot detect the relatively small elevations of CRP that are associated with increased cardiovascular risk.

A Complete Blood Count (CBC) Panel is used as a screening test for various disease states including anemia, leukemia, and inflammatory processes.

A CBC blood test includes the following biomarkers: WBC, RBC, Hemoglobin, Hematocrit, MCV, MCH, MCHC, RDW, Platelet count, Neutrophils, Lymphs, Monocytes, Eos, Basos, Neutrophils (Absolute), Lymphs (Absolute), Monocytes(Absolute), Eos (Absolute), Basos (Absolute), Immature Granulocytes, Immature Grans (Abs)

NOTE: Only measurable biomarkers will be reported.

CBC Reflex Pathway

Step 1 - The slide review is performed by qualified Laboratory staff and includes:

  • Confirmation of differential percentages
  • WBC and platelet estimates, when needed
  • Full review of RBC morphology
  • Comments for toxic changes, RBC inclusions, abnormal lymphs, and other
  • significant findings
  • If the differential percentages agree with the automated counts and no abnormal cells are seen, the automated differential is reported with appropriate comments

Step 2 - The slide review is performed by qualified Laboratory staff and includes: If any of the following are seen on the slide review, Laboratory staff will perform a manual differential:

  • Immature, abnormal, or toxic cells
  • nRBC’s
  • Disagreement with automated differential
  • Atypical/abnormal RBC morphology
  • Any RBC inclusions

Step 3 If any of the following are seen on the manual differential, a Pathologist will review the slide:

  • WBC<1,500 with abnormal cells noted
  • Blasts/immature cells, hairy cell lymphs, or megakaryocytes
  • New abnormal lymphocytes or monocytes
  • Variant or atypical lymphs >15%
  • Blood parasites
  • RBC morphology with 3+ spherocytes, RBC inclusions, suspect Hgb-C,
  • crystals, Pappenheimer bodies or bizarre morphology
  • nRBC’s

Comprehensive Metabolic Panel


A synthetic circular peptide containing citrulline called CCP IgG (cyclic citrullinated peptide) has been found to be better at discriminating Rheumatoid Arthritis patients from other patients than either the perinuclear autoantibody test or the test for rheumatoid factor. Approximately 70% of patients with Rheumatoid Arthritis are positive for Anti-CCP IgG, while only about 2% of random blood donors and disease controls subjects are positive.

A lipid panel includes:Total cholesterol —this test measures all of the cholesterol in all the lipoprotein particles.High-density lipoprotein cholesterol (HDL-C) — measures the cholesterol in HDL particles; often called "good cholesterol" because it removes excess cholesterol and carries it to the liver for removal.Low-density lipoprotein cholesterol (LDL-C) — calculates the cholesterol in LDL particles; often called "bad cholesterol" because it deposits excess cholesterol in walls of blood vessels, which can contribute to atherosclerosis. Usually, the amount of LDL cholesterol (LDL-C) is calculated using the results of total cholesterol, HDL-C, and triglycerides.Triglycerides — measures all the triglycerides in all the lipoprotein particles; most is in the very low-density lipoproteins (VLDL).Very low-density lipoprotein cholesterol (VLDL-C) — calculated from triglycerides/5; this formula is based on the typical composition of VLDL particles.Non-HDL-C — calculated from total cholesterol minus HDL-C.Cholesterol/HDL ratio — calculated ratio of total cholesterol to HDL-C.

Elevated RF is found in collagen vascular diseases such as SLE, rheumatoid arthritis, scleroderma, Sjögren's Syndrome, and in other conditions such as leprosy, tuberculosis, syphilis, malignancy, thyroid disease and in a significant percentage of otherwise normal elderly patients.

Useful in differentiating inflammatory and neoplastic diseases and as an index of disease severity. CRP is also useful in monitoring inflammatory disease states.


Did you know over 54 million adults in the US have osteoarthritis (OA)? In addition, over 24 million adults are limited in the activities they can do because of OA.

When you're in pain, it's all too easy to feel alone. But you can take charge of your symptoms by getting the osteoarthritis tests you need to get the answers you deserve.

Remember, there is help available for the pain that osteoarthritis brings. But your most powerful tool is educating yourself about OA and what you can do to manage your symptoms.

So if you want to learn more about osteoarthritis and osteoarthritis tests, keep reading this guide to find out everything you need to know!

What is Osteoarthritis

Osteoarthritis is the most common form of arthritis. Osteoarthritis occurs when the cartilage that protects your joints wears down over the years. 

Cartilage is the slippery tissue that allows your joints to remain moving in a fluid motion. When your cartilage breaks down, it enables your bone to surfaces to become rough and jagged. 

Cartilage doesn't have blood vessels or blood supplies, so for this reason, damaged cartilage can't repair itself.

Osteoarthritis can occur in any joint, but it's most common in your spine, hips, hands, and knees.

It's vital to remember OA is progressive. OA progresses in stages from 0 to 4. The first stage indicates a normal joint, and stage 4 means severe OA. As OA goes through the stages, you'll have increased pain, swelling, inflammation, decreased range of motion, and unstable joints.

Causes of Osteoarthritis

Osteoarthritis is often referred to as wear and tear disease.  As you age, your joints naturally start to break down.

But there are risk factors and other disease conditions that put you at higher risk for developing OA.

Risk factors for Osteoarthritis

Risk factors that can make osteoarthritis a reality include:

Obesity is one of the most significant risk factors as it puts extra stress on your joints, especially the knees and hips.

Past joint injuries or surgery can put you at greater risk for OA, as can congenital joint abnormalities at birth.

A job or hobby that requires you to make repeated motions over and over again can increase your chances of getting OA.

If you have had a joint inflammatory condition like rheumatoid arthritis, it can lead to your joints breaking down faster.

Diabetes and changes in hormone levels can cause inflammation and lead to arthritis. And menopause brings changes to the estrogen levels that protect your bones and joints. Once estrogen levels fall, you're at higher risk for OA.

Osteoarthritis Symptoms

When you have osteoarthritis, the symptoms slowly worsen in time in stages. But when you have osteoarthritis, you'll notice things like:

  • Joint pain with movement
  • Joint stiffness, especially after waking up in the morning
  • Your joints lose flexibility
  • Your joints feel tender upon touch
  • You may notice your joints pop and crack
  • Joint swelling

Sometimes extra bits of bone (bone spurs) form around your joints which feel like hard lumps. If your joint pain and stiffness won't let up, then it's time to contact your doctor.

Complications of Osteoarthritis

Osteoarthritis is degenerative, meaning it continues to get worse over time. Joint pain can become severe, making daily tasks almost impossible.

Osteoarthritis Treatment

The damage from osteoarthritis can't be reversed, but treatments are available to reduce your joint pain and improve your quality of life.

The first line of treatment includes medications to help relieve your symptoms. Your doctor will typically recommend over-the-counter medicines like Tylenol, Advil, or prescription anti-inflammatory medication, depending on your situation.

The next line of treatment involves physical therapy for exercises to strengthen the muscles around your joint and improve flexibility.

You may also need occupational therapy if you're having trouble with everyday tasks. An occupational therapist will help you learn different ways of moving to put less stress on your joints.

Some people might need assistive devices like a bench in the shower to alleviate the strain.

If medications and therapy don't work for you, other treatments are available, like steroid injections into your joints. In severe cases, joint replacement surgery may be the best solution.

Lifestyle Changes

One of the most important things you can do to manage the symptoms and progression of OA is making lifestyle changes. Exercise and weight loss go a long way in reducing the pain and stiffness that come with OA.

Gentle exercise like swimming or walking is a great way to keep active. You can also try biking or water aerobics. But the important thing is to make it a part of your daily routine. The worst thing you can do when you have OA is sitting and not moving.

When you carry extra weight, you put stress on your already arthritic joints. Even losing just 10lbs can make a massive difference for your joints. If you struggle with weight, talk to your doctor or a dietician to help you come up with a plan.

Other options

Yoga, tai chi, and deep breathing work amazingly well to improve your joint flexibility and stress at the same time. Choose yoga that's gentle and easy and avoid any movements that stress your joints.

Applying both heat and cold to your joints can relax your muscles and reduce pain. You can do this after exercise or at the end of the day.

Some people also find relief from using Capsaicin cream. Capsaicin is the active ingredient in chili peppers, and when applied as a topical cream, it can change the way your body responds to pain. 

Many people find relief using this cream, but it can cause some skin irritation. So talk to your doctor first if you think it might be for you.

Osteoarthritis Diagnosis

You'll first see your doctor and have a physical exam. Your doctor will check your joints for tenderness, swelling, and redness.

To get a clear picture of your joints, your doctor may order X-rays to rule out any other problems. If you have severe symptoms, you might also have an MRI to look at your bones and soft tissues.

Although there isn't one single blood test that can diagnose arthritis, your doctor will order a series of blood tests to rule out other issues like rheumatoid arthritis.

Lab Tests for Osteoarthritis

In general, the goal of ordering a blood osteoarthritis test is to distinguish osteoarthritis from other inflammatory or autoimmune conditions.

comprehensive Osteoarthritis panel from Ulta Lab Tests is a great way to get all the tests you need.

First, your doctor will want to check your rheumatoid factor (RF). This test will determine if your symptoms are caused by rheumatoid arthritis RA instead. Your rheumatoid factor will be negative with RA.

Another test commonly ordered is an Erythrocyte sedimentation rate (ESR) test. The ESR detects inflammation in your body and will be increased with RA, but not with osteoarthritis. Also, a C-reactive protein (CRP) detects inflammation and is elevated with RA.

Your doctor will also check your complete blood count (CBC) and comprehensive metabolic panel (CMP). These panels will assess your overall health status and see how well you'll be able to tolerate any OA medications you might need.

Sometimes your doctor may want to do a joint fluid analysis. OA, infections, and other inflammatory conditions can change the way your joint fluid appears. Fluid is drawn out from your joint and analyzed under a microscope.

Osteoarthritis FAQS

Did you know osteoarthritis is the leading cause of disability in the United States, and more women are more likely to develop OA than men?

Joint surgery is effective and considered to be one of the most successful operations in medicine today. For example, if you get hip replacement surgery, you have over a 95% chance of success at a full recovery. 

You've likely heard that cracking your joints causes arthritis? This is a myth, so you don't have to worry that your knuckle-cracking habit will land you with OA.

It's also a myth that osteoarthritis isn't a serious health problem. While OA may take a back seat to cancer and heart disease, it still affects over 50 million people a year and with healthcare costs of over 150 billion.
