Aluminium poisoning occurs when people are exposed to high quantities of aluminium
compounds. Aluminium poisoning has complex and multidimensional effects, such as:

• Disrupting or inhibiting enzyme activities
• Altering protein synthesis
• Nucleic acid function
• Cell membrane permeability
• Preventing DNA repair
• Altering the stability of DNA organisation
• Increasing reactive oxygen species (ROS) production
• Inducing oxidative stress
• Decreasing antioxidant enzyme activity
• Altering cellular iron homing

What is a spot urine test?

When your doctor suspects you have kidney disease, they will most likely order this test.
Additionally, it can be used to check for renal disease, for instance in diabetics. Even though
there are always trace levels of protein in the urine, a regular dipstick test may miss them.

What Aluminium, Spot Urine Test Diagnose?

Aluminium testing is a common procedure to check for aluminium toxicity in dialysis patients.
Checking metallic implant ware for prosthetics is also beneficial.

This test I used in the evaluation of previous and ongoing aluminium exposure. Especially in
newborns on parenteral fluids, burn patients receiving arterial albumin, adult and paediatric
patients with chronic kidney disease, patients receiving parenteral nutrition, and industrial
employees. Spot urine is an appropriate sample type to use if 24-hour urine collection is not
possible to track aluminium exposure and the deterioration of metallic prosthetic implants.

Under typical physiologic circumstances, the typical daily dietary intake of aluminium (5–10
mg) is entirely removed. Aluminium from the blood is actively filtered by the kidney's
glomeruli to produce excretion. Aluminium poisoning is a risk for patients with kidney failure
because they cannot remove it from their bodies. In patients with kidney failure, aluminium
poisoning is more common for a variety of reasons:

• Patients on dialysis may be exposed to aluminium through their dialysis water.
• Patients who get aluminium-containing albumin risk being exposed to a burden they
  are unable to remove.
• The dialysis procedure does not remove metal very well.
• Aluminium-based phosphate binder gels are administered orally to minimize
  phosphate accumulation; a small fraction of this aluminium may be absorbed and
  accumulated.

If renal filtration does not eliminate it, aluminium builds up in the blood, where it binds to
proteins like albumin and is swiftly transported throughout the body. Aluminium overload
causes the accumulation of aluminium in the brain and bones. Brain deposition has been
identified as the root cause of dialysis dementia. Aluminium replaces calcium at the bone's
mineralization front, impairing osteoid growth normally.

Urine aluminium concentrations in patients with metallic joint prostheses are likely to rise
over the recommended level. Titanium, aluminium, and vanadium are frequently used in the
manufacture of prosthetic devices by Zimmer Company and Johnson and Johnson. For
further information on each product's composition, read the prosthetic product information for
that particular device as this list of items is not complete and these products occasionally
change.

Who should take the Aluminium, Spot Urine Test?

The production of alloys, window frames, engine and aeroplane parts, roofing, electrical
lines, and many more industrial activities all need aluminium.

By inhaling fumes and tiny dust particles, aluminium is mostly absorbed through the lungs.
When substantial quantities of high aluminium-containing substances, such as antacids, are
taken, some aluminium is absorbed through the digestive tract. Although some of it is also
eliminated in the bile, urine is the primary method of elimination.

Workers who are exposed to dust and fumes at work are monitored using urine aluminium
measurement. Among exposed workers, welders have the greatest excretion rates.

High quantities of it may be ingested by people when they:

• Intake of high-concentration foods or beverages containing aluminium.
• Air pollution from the mining or processing of aluminium can be inhaled during work.
• Live close to some locations that contain hazardous waste
• reside in an area where there is a lot of aluminium naturally

Symptoms

Individuals who are toxic to aluminium may:

• Unstable mind
• Muscle soreness
• aching, deforming, or broken bones
• Seizures
• communication issues
• Slow development (in children)

Severe signs and symptoms without treatment could result in:

• Lung issues
• Issues with the stomach and bowels
• Movement troubles are brought on by nervous system disorders
• Bone disorders
• Conditions that affect the brain
• Anemia

Procedure and parathion of the test

Antacids and drugs containing aluminium are advised to be avoided by patients before the
test. The metal tests are known to be affected by high concentrations of gadolinium and
iodine. Therefore, it is advised to wait 96 hours before collecting any material containing
gadolinium or iodine. Use only the designated LPL containers for the test, as per the
instruction.

Follow the instructions given by your physician to collect urine.

• Clean the region surrounding the urine entrance.
• Urinate into the toilet and begin.
• Follow midstream stopping
• Allow a flow of 1-2 ounces into the container.
• In the bathroom, finish peeing.
• Pay attention to your doctor's instructions while submitting the sample.
• For babies and other people unable to provide a sample in this way, a doctor may
  have to insert a soft, narrow tube called a catheter through the urinary opening and
  into the bladder.

Results of Aluminium, Spot Urine Test

Normal levels:

The normal aluminium range can be between 1 and 3 g/L and 5 to 10 mg/kg for healthy
people.

• Aluminum, Urine - ug/day 0-10 µg/d
• Aluminum, Urine - ug/L 0.0-7.0 µg/L

High levels:

The range above the normal levels indicates excessive aluminium exposure that needs to be
addressed.

A prosthetic device in good condition may be linked to a little increase (10–20 mcg/24 hours)
in urine aluminium concentration. Significant prosthesis wear is indicated by urine
concentrations exceeding 50 mcg/24 hours in patients with aluminium-based implants who
are not receiving dialysis.

What specimens are unaccepted for the test?

• After administering gadolinium (Gd)-containing contrast medium, urine must be
  collected within 48 hours (may occur with MRI studies).
• Urine stored in acid containers is not accepted.
• Specimens that have been tainted by faeces or blood. specimens conveyed in a tube
  containing traces of elements (except the original device) are not accepted for the
  test.
