Lyme Disease Testing: When to Get It and What Your Results Mean

Have you ever felt dismissed after a doctor told you your labs were “normal,” despite still feeling unwell? You’re not alone. At Novalab Corp in Wayne, NJ, we specialize in uncovering what traditional lab tests often miss—immune responses to everyday foods that could be silently fueling your symptoms.

Early detection can make a significant difference in how Lyme disease is treated and managed. Knowing when to seek testing—and understanding your results—empowers you to act quickly and take charge of your health.

Recognizing Lyme Disease Symptoms

Lyme disease doesn’t always present the same way in every person, which is why it’s often overlooked in its early stages. Symptoms can start within 3 to 30 days of a tick bite but may develop gradually or resemble other common conditions.

Early symptoms may include:

  • Fatigue
  • Fever and chills
  • Headaches
  • Muscle or joint aches
  • Swollen lymph nodes
  • A circular or bullseye-shaped rash near the bite site (known as erythema migrans, though not everyone gets this rash)
If left untreated, the infection can spread and lead to:
  • Severe joint pain and swelling
  • Neurological symptoms (such as facial drooping or nerve pain)
  • Irregular heartbeat or dizziness
  • Cognitive difficulties or memory issues
Because Lyme disease mimics other illnesses, it’s crucial to pay attention to these symptoms—especially if you’ve recently been in wooded, grassy, or tick-prone areas.

When to Consider Lyme Disease Testing

Timing is everything when it comes to Lyme disease testing. Testing too early—before the body has produced detectable antibodies—can lead to false-negative results. That said, some tests like PCR can detect the presence of bacterial DNA early in the infection.

You should consider Lyme disease testing if you:

  • Develop symptoms within days or weeks of a tick bite
  • Don’t recall a tick bite but start showing consistent symptoms after spending time in wooded or grassy environments
  • Experience symptoms that resemble Lyme disease but haven’t responded to typical treatments
  • Have a history of chronic fatigue, unexplained joint pain, or neurological symptoms without a clear cause
If symptoms are present and there’s a reasonable suspicion of tick exposure, early testing—guided by your provider—can help catch the infection before it becomes more difficult to manage.

Understanding the Types of Lyme Disease Tests

There isn’t a one-size-fits-all approach to Lyme disease testing. Different tests are used depending on the stage of the illness and how long it’s been since potential exposure.

1. PCR Lyme Test (Polymerase Chain Reaction)

This advanced diagnostic tool detects the genetic material (DNA) of Borrelia burgdorferi. PCR is particularly useful in the early stages of infection or when symptoms point to Lyme but standard antibody tests are inconclusive.
  • Best used for: Early detection or ongoing symptoms that don’t match standard serology results
  • Sample type: Typically blood, sometimes spinal fluid or joint fluid
  • What it shows: Active infection through direct bacterial presence
  • Note: False negatives can still occur if bacterial levels are very low in the sample

2. ELISA (Enzyme-Linked Immunosorbent Assay)

This blood test checks for antibodies the body produces in response to Lyme bacteria. A positive ELISA result typically requires confirmation.
  • Best used for: Detection weeks after exposure (antibodies take time to develop)
  • What it shows: Immune system response to infection

3. Western Blot

Often used to confirm a positive ELISA result, this test identifies specific proteins (antibodies) related to Lyme disease.
  • Best used for: Confirming diagnosis in later stages
  • What it shows: More detailed evidence of exposure based on immune response

Interpreting Lyme Test Results in Context

A single lab result doesn’t always give the full picture. Lyme disease testing should always be interpreted alongside your symptoms, exposure history, and how long it’s been since potential infection.
  • Positive PCR test: Indicates the presence of Borrelia DNA and supports active infection
  • Negative PCR test with symptoms: Doesn’t entirely rule out Lyme—retesting or antibody testing may be needed
  • Positive ELISA and Western Blot: Confirms immune response and supports diagnosis
  • Negative antibody tests early on: May need to be repeated after a few weeks if symptoms persist
Some patients may test negative but still experience symptoms. In these cases, clinical judgment plays a key role in deciding treatment options.

Taking the Next Step

Prompt testing is critical when Lyme disease is suspected. The sooner it’s identified, the more effective treatment can be—often with a simple course of antibiotics that prevents long-term complications. Delayed diagnosis, however, can lead to more persistent and complex issues.
