Red Blood Cell Zinc (RBC Zinc) Blood Test

$115.00 AUD

Experiencing frequent infections, slow wound healing, or skin issues and want accurate assessment of zinc status for immune function and cellular health?

The Red Blood Cell Zinc Test measures zinc stored inside red blood cells, giving a more accurate picture of long-term zinc status than standard blood zinc tests. Adequate zinc supports immunity, hormone balance, metabolism, and healing, while low levels may lead to fatigue, poor immunity, and reproductive issues.

This test is only available at Healius collection centres.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"

Overview

Your red blood cells are like tiny storage units that hold onto zinc where your body actually uses it – inside your cells rather than just floating around in your bloodstream. The RBC Zinc test acts as your body's zinc detective, checking these cellular storage units to see if you truly have enough of this essential mineral. Unlike regular blood tests that only measure zinc in your serum (the liquid part of blood), this test looks inside your red blood cells where zinc does its real work supporting your immune system, healing wounds, and keeping your cells functioning properly.

This deeper look matters because your body is quite the master of disguise – it can keep zinc levels looking normal in your bloodstream even when your cells are running low, kind of like maintaining a good-looking storefront while the back warehouse is nearly empty. When your cellular zinc levels drop, you might notice frequent colds, wounds that heal slowly, hair loss, or skin issues. The RBC Zinc test helps catch these hidden deficiencies that standard tests might miss, making it especially valuable if you're dealing with recurring infections, following a vegetarian diet, have digestive issues, or want to make sure your zinc supplements are actually reaching your cells where they're needed most.

Symptoms

Essential for individuals with immune dysfunction, wound healing issues, suspected zinc deficiency, or anyone needing accurate intracellular zinc assessment.

Questions

  • RBC zinc better reflects tissue stores and functional zinc status, as serum levels may not accurately represent cellular zinc availability for immune and metabolic functions.
  • Signs include frequent infections, slow wound healing, hair loss, skin problems, poor appetite, altered taste or smell, and impaired immune function.
  • Causes include poor dietary intake, gastrointestinal disorders, vegetarian diets, certain medications, chronic diseases, and increased zinc requirements during growth or illness.
  • Daily requirements vary but generally range from 8-11mg for adults, with higher needs during pregnancy, breastfeeding, illness, or periods of rapid growth.
  • Good sources include oysters, red meat, poultry, beans, nuts, seeds, dairy products, and fortified cereals, with animal sources being more bioavailable.
  • Yes, excessive zinc can interfere with copper absorption, impair immune function, and cause other health problems, so appropriate dosing and monitoring are important.

How to prepare

No special preparation required. Inform healthcare provider of all zinc supplements and medications that might affect zinc levels. Consider timing relative to recent supplementation.

After the test

Address low RBC zinc through appropriate zinc supplementation, dietary improvements including zinc-rich foods, addressing underlying absorption issues, and regular monitoring to achieve optimal cellular levels.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Results show RBC zinc levels compared to optimal ranges. Low levels indicate cellular zinc deficiency requiring supplementation, while optimal levels suggest adequate intracellular zinc for immune function.

Frequently Asked Questions

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

Just your pathology referral form (we email it to you)

Of course. Just maybe don’t bring the friend who faints at the sight of blood.
