How to read lead blood test results?

Welcome folks! Today, we’re going to talk about how you can read lead blood test results like a pro. With the ever-rising cases of lead poisoning in our neighborhood, it’s more important than ever to keep an eye on our health and wellbeing.

But here’s the thing: reading medical reports isn’t exactly fun, is it? All those technical terms and abbreviations – they might as well be written in ancient Greek for all we care. Fear not though, my friend! In this article, I’ll help you make sense of your lead blood test results – with some humor thrown into the mix.

What is Lead Poisoning?

Before we dive into interpreting those numbers in your report, let’s first understand what lead poisoning is all about.

Lead is a toxic metal that was once commonly used in household items such as paint and pipes. Exposure to high levels of lead can cause serious health problems including brain damage and even death.

Contrary to popular belief, nobody goes around munching on paint chips anymore (we hope). Nowadays, most people are exposed to lead through contaminated water or dust from old buildings. So if you live or work in an older home or building (that hasn’t been properly maintained), you’re at risk of being exposed to lead.

Fun Fact: Did you know that Leonardo Da Vinci died due to exposure from his own artwork? The red pigment he used contained high amounts of toxic mercury!

Understanding Your Lab Report

Okay then, let’s move on now that we’ve gained some basic knowledge about why checking for lead toxicity matters. You’ve got your lab report- congrats! But where do we start? Let me break it down:

CBC with Differential

The Complete Blood Count (CBC) with differential measures various components present in your total blood sample; this may include white cells count(WBCs), platelets, mean red cell volume (MCV), with differential to measure the different types of white blood cells. Now take a look at your CBC report:

  • WBC Count: WBC stands for White Blood Cell count. This measures the number of white blood cells present in your body’s immune system.

  • RBC Count: RBC Stands for Red Blood Cell count or also referred as Hemoglobin(Hb). It signifies how well are oxygen being transported by our body

The Results for Lead Poisoning Test

Great! You could find “Serum lead test” line in your report or even it is renamed to “Blood lead test.” A simple explanation – this section measures the amount of lead present in your bloodstream expressed as micrograms per deciliter (µg/dL).

Did you get lost after all these medical terminologies? Well, let me rephrase that whole paragraph into an easy-to-understand point: this part tells us if there’s any toxic waste wandering around in our veins and how much they’re lurking!

Normal Levels vs Elevated Levels

So you looked through those numbers and saw that beside kudos on maintaining a healthy routine; everything looks within normal range. Or did it?

In various countries, their standard reference value may differ but usually agreed upon normal level ranges from 0-5 µg/dL.

However, when we talk about elevated levels of serum/blood/lead testing, greater than 10 µg/dL is considered alarming when tested recurrently at certain intervals less than every six months.

Caveat Alert: When pregnant women cross more than five µg/dL limits – states have specific public health governance protocols since developmental delays pertaining kids can occur.

So How Do We Interpret These Results?

We’ve come down to the real explainer here.

A) Zero Level Reading:
If reports show findings within nil reports region i.e. 0 µg/dL, congratulations! Smile as you’re stress-free from poisonous lead exposure.

B) Elevated Level Reading:
If the reading crosses the normal level of five microgram per deciliter (5µg/ dL), – relaxation time is over.

  • Mildly elevated levels:
    Going up by just one notch above the normal range might not be a signal alarm at all times but it’s always good to keep regular checkups and take informed preventive measures.

  • Moderately elevated levels:
    When we talk about results in between fifteen µg and thirty-five µg/dL – these are considered moderate category readings that require a physician’s investigation plans; this could include changes to home or workplace environment, specific medication if deemed necessary.

  • Highly Elevated Levels:
    Unfortunately, if your reports exceed greater than thirty-fiveµg /dLand doesn’t show signs of decreasing overtime needs immediate evaluation for more advanced treatment options and reporting protocols.

Exposure & Treatment Plan

So what happens next? Your blood test report shows an elevated reading which reflects that somehow during household routine tasks or even outdoor activities have made it possible to get exposed.


The first thing you should do after receiving the report is consult with your medical practitioner who can recommend proper guidance based on his/her expertise. As every individual case differs from person-to-person there can’t be any cookie-cutter approach adopted.

But here are some general tips to mitigating further exposure:

Modify Environmental Exposures

You wouldn’t want yourself nor your family getting new findings popping up again right?

  1. Find out sources- Check for potential sources such as contaminated old paint chips, pipes containing higher percentage of water pipe tanks.

  2. Stick with clean drinking water- Ensure consuming potable/muncipal supply insteadof taking filtered tap

  3. Prevent Making Mistakes With Imported Items
    Curtail the usage of imported products which comes from countries having less or no lead laws.

Chelation Therapy (Lead Poisoning Treatment)

Chelation therapy helps remove heavy metals including lead from your bloodstream through a series of intravenous infusions administered under medical supervision. Usually prescribed when levels show moderately elevated readings but effectiveness solely depends on individual patient case-to-case basis.


There you have it folks, here’s all you need to know about reading those pesky lead blood test reports! Hopefully, by now, you’ve got an idea about what each section and number means for healthy living plans.

The best practice is to always consult with a doctor when it comes to interpreting these results as they will be able to offer more personalized advice according to your body chemistry or metabolism functions.

Keeping our environment clean and awareness towards household chemicals or even regular food intake patterns can prevent us from encountering further exposure or risk prediction.

Remember this – A little focus on health consciousness goes a long way in preventing major issues; so make sure that next time testing time arrives–-you’re ready with concise knowledge at hand while keeping the excitement higher than reading Da Vinici’s innermost secrets off his paintings Huh!?
