Blood and Pathology Tests in Grand Rapids, Michigan

Blood and pathology tests can make many people in Grand Rapids feel a bit uneasy, but they’re one of the most important tools doctors use to detect, diagnose, and monitor disease. If you’re feeling unwell, or managing a chronic condition, many decisions about your care at Spectrum Health, Trinity Health Grand Rapids, Metro Health, or Mercy Health will be based on your blood and pathology test results.

“Pathology” simply means the study of disease—its causes, how it develops, and how it affects the body.

What Are Blood and Pathology Tests?

Pathology tests include:

  • Blood tests
  • Urine tests
  • Stool (feces) tests
  • Tests on body tissues or cells (biopsies, Pap smears, etc.)

A pathologist is a specialist doctor who interprets these test results and looks for abnormalities that may point to disease.

Main Types of Pathology

In Grand Rapids and across Michigan, pathology services are typically provided through hospital labs and independent pathology services. Major branches include:

  • Anatomical pathology
    Examines body tissues (often surgically removed) to diagnose conditions such as cancers, inflammatory diseases, and infections.

  • Cytopathology
    A subspecialty of anatomical pathology that looks at individual cells (for example, Pap smears for cervical cancer screening).

  • Forensic pathology
    Investigates sudden, unexpected, or suspicious deaths, often working with law enforcement.

  • Clinical pathology
    Uses laboratory testing of blood, urine, and other body fluids to diagnose and monitor disease.

  • Chemical pathology (clinical chemistry)
    Analyzes chemicals in blood and other fluids (like glucose, cholesterol, electrolytes, and enzymes).

  • Hematology
    Focuses on blood disorders, such as anemia, clotting problems, and blood cancers like leukemia.

  • Medical microbiology
    Investigates infections caused by bacteria, viruses, fungi, and parasites.

  • Immunopathology
    Studies immune system responses, including autoimmune diseases and allergies.

  • Genetic pathology
    Looks at inherited and genetic diseases, including some cancers and metabolic conditions.

  • General pathology
    Covers multiple aspects of laboratory investigation of disease.

Why Your Grand Rapids Doctor Might Order Blood and Pathology Tests

If your Grand Rapids primary care doctor or specialist orders blood or pathology tests, it’s usually because:

  • There is a concern about your current health
  • You’re at an age or life stage where certain risks are higher
  • You have risk factors common in West Michigan (such as family history of heart disease, diabetes, or certain cancers)
  • You’re pregnant or planning a pregnancy
  • You need monitoring for a known condition or medication

Common Reasons for Testing

Your doctor may order tests to:

  • Screen for disease

    • Detect conditions early, even before symptoms appear
    • Examples:
      • Bowel cancer screening (especially age 45+)
      • Pap smears for cervical cancer
      • Cholesterol and blood sugar checks for heart disease and diabetes risk

  • Diagnose an illness

    • Identify the cause of symptoms like fatigue, weight changes, pain, or infections
    • Confirm or rule out conditions such as anemia, thyroid disease, kidney or liver problems, or autoimmune disease

  • Assess health risks

    • Evaluate your risk of future disease (for example, high cholesterol, pre-diabetes, or inherited conditions)

  • Monitor a known condition

    • Track how diseases such as diabetes, heart disease, kidney disease, or cancer are progressing
    • Adjust treatment plans based on results

  • Plan treatment or surgery

    • Check your blood type before transfusion or surgery
    • Ensure your organs are functioning well enough for certain medications or procedures

  • Monitor medications

    • Measure drug levels (for example, warfarin)
    • Check for medication side effects on your liver, kidneys, or bone marrow

In a city like Grand Rapids—with cold winters, variable weather, and common Midwest health concerns like heart disease, diabetes, and seasonal infections—these tests help doctors tailor care to local risks and your personal health history.

Screening vs. Investigative Tests

Screening Tests

Screening uses simple tests in people who feel well, to find disease early—before symptoms start.

Examples relevant to Grand Rapids residents include:

  • Bowel cancer screening (typically starting at age 45 or as advised)
  • Pap smears for cervical cancer in women
  • Mammograms for breast cancer
  • Early prenatal (antenatal) tests to screen for risks to the baby or mother

Screening programs may be supported by national guidelines and local resources like the Kent County Health Department and Grand Rapids Public Health.

The goal is early detection, when treatment is often more effective and less invasive.

Investigative (Diagnostic) Tests

Investigative tests are done when:

  • You already have symptoms (such as pain, fever, fatigue, weight loss, or bleeding)
  • Your doctor has concerns based on your exam or history
  • Previous screening tests were abnormal

These tests are individualized—they are not for the general population but for specific people with specific concerns.

Common Blood and Pathology Tests in Grand Rapids

When you visit a Grand Rapids clinic, hospital, or lab, you may be sent for some of the following common tests. Results are usually interpreted alongside your age, sex, lifestyle, medical history, and local risk factors (for example, higher winter inactivity or seasonal infections).

Full Blood Count (FBC or CBC)

A full blood count (also called a complete blood count, CBC) measures:

  • Red blood cells (carry oxygen)
  • White blood cells (fight infection)
  • Platelets (help blood clot)
  • Hemoglobin and other indices

Abnormalities may indicate:

  • Anemia (often causing fatigue and low energy)
  • Infection
  • Some blood cancers, such as leukemia
  • Inflammation or immune disorders

Liver Function Tests (LFTs)

Liver function tests measure enzymes, proteins, and other substances made or processed by your liver.

They help detect:

  • Liver inflammation or damage
  • Infections such as hepatitis
  • Alcohol-related liver disease
  • Fatty liver (increasingly common with obesity and diabetes)
  • Side effects from medications

Early detection is important to prevent long-term liver damage.

Iron Studies

Iron studies assess:

  • How much iron is in your blood
  • How your body stores and uses iron

They help diagnose:

  • Low iron (iron deficiency) – often causing anemia, fatigue, and weakness
  • Too much iron (iron overload or hemochromatosis) – which can increase the risk of:
    • Liver disease
    • Heart failure
    • Arthritis
    • Diabetes

Hemochromatosis is more common in people of Northern European ancestry, a group well-represented in West Michigan.

Thyroid Stimulating Hormone (TSH) Test

The TSH test checks how well your thyroid is working.

It is used to diagnose or monitor:

  • Hypothyroidism (underactive thyroid – insufficient thyroid hormone)
  • Hyperthyroidism (overactive thyroid – excess thyroid hormone)
  • Some autoimmune conditions (like Hashimoto’s disease or Graves’ disease)

Thyroid hormones help control:

  • Breathing
  • Heart rate
  • Body weight
  • Body temperature
  • Energy levels

Because seasonal changes and low sunlight in Michigan winters can affect energy and mood, doctors may check thyroid function when you report fatigue, weight changes, or low mood.

Urinalysis (Urine Test)

A urinalysis is a set of tests on a urine sample. It can help detect:

  • Kidney disease
  • Liver disease
  • Diabetes
  • Urinary tract infections (UTIs)
  • Pregnancy (when a pregnancy test is done)

Your doctor may also do a rapid urine test in the office using a dipstick for quick results.

INR (International Normalized Ratio)

The INR test measures how quickly your blood clots.

It is especially important if you’re taking warfarin or other blood-thinning medications, often prescribed in Grand Rapids for:

  • Atrial fibrillation (to prevent stroke)
  • History of blood clots (DVT, pulmonary embolism)
  • After certain surgeries

INR testing helps your doctor adjust your dose to keep you safe from both clots and excessive bleeding.

What to Expect During Common Pathology Test Procedures

Blood Test Procedure

Most blood tests in Grand Rapids are done at:

  • Hospital outpatient labs (Spectrum Health, Trinity Health Grand Rapids, Metro Health, Mercy Health)
  • Independent pathology collection centers
  • Larger medical practices and clinics

Typical steps:

  1. Check-in at the lab or collection center.
  2. You may be asked to sit or lie down.
  3. The person collecting your blood (a phlebotomist, nurse, or other trained professional) will:
    • Place a tourniquet around your upper arm to make the veins more visible
    • Ask you to clench and unclench your fist a few times
    • Clean the skin with an antiseptic wipe
    • Insert a small needle into a vein, usually in your arm
  4. Blood flows into one or more tubes.
  5. You may feel a brief sting or mild discomfort.
  6. Afterward, you’ll be asked to press a cotton ball or gauze on the site, and a small bandage will be applied.
  7. Mild bruising can occur and usually fades within a few days.

Tell the phlebotomist if:

  • You’ve fainted with blood draws before
  • You feel dizzy or unwell
  • You have concerns about pain or needles

Urine Sample Collection

You may be asked to provide a urine sample:

  • At your doctor’s office
  • At a lab in Grand Rapids
  • At home, with instructions to return or mail the sample

You’ll usually be given a small sterile container.

For a midstream urine sample (commonly requested):

  1. Start urinating into the toilet.
  2. Move the container into the stream midway through urination.
  3. Collect enough urine to fill the container as instructed.
  4. Finish urinating into the toilet.
  5. Secure the lid tightly.
  6. Wash your hands thoroughly after collecting your sample.

If you’re at the clinic, your doctor may perform a rapid urine test immediately using a dipstick. If collecting at home, follow the instructions about storage and how soon to deliver the sample to the lab.

Stool (Feces) Sample Collection

Stool samples are usually collected at home with a test kit.

Typical steps:

  1. You may be given:
    • Gloves
    • A small collection container with a lid
    • A scoop or spatula
  2. It’s usually best to urinate first, so urine doesn’t mix with the stool.
  3. Collect the stool:
    • Use a clean container, or
    • Place newspaper or plastic wrap over the toilet bowl to catch the stool
  4. Use the provided scoop to place a small amount of stool (often about one-third of the container) into the sample container.
  5. Avoid:
    • Letting the stool touch the inside of the toilet bowl
    • Mixing toilet water with the sample
  6. Screw the lid on tightly.
  7. If instructed, clearly label the container with:
    • Your name
    • Date of birth
    • Date and time of collection
  8. Follow instructions on how to return the sample to your doctor or lab.
  9. Discard any used collection materials safely and wash your hands thoroughly.
