We measure before we treat anything.

Your immune system's front line; high or low can signal infection, inflammation, or stress on the body.

The cells that carry oxygen; testosterone therapy can raise this, so we watch it closely.

The protein inside red cells that actually holds the oxygen; a key safety marker on TRT.

How much of your blood is red cells; the number one marker we monitor to keep testosterone therapy safe.

The average size of your red cells; helps spot B12, folate, or iron problems early.

How much hemoglobin each red cell carries; another early flag for nutrient deficiencies.

How concentrated the hemoglobin is inside each cell; rounds out the anemia picture.

How much your red cells vary in size; rising variation can catch deficiencies before symptoms do.

The cells that clot your blood; too low or too high matters before any protocol starts.

The average size of your platelets; context for how your clotting system is performing.

Your bacteria-fighting white cells as a share of the total.

Your virus-fighting and immune-memory cells as a share of the total.

The cleanup crew of the immune system; elevated can mean lingering inflammation.

The allergy and parasite responders; high often points to allergies.

The rarest white cells, involved in allergic and inflammatory responses.

The actual count of bacteria-fighters, not just the percentage.

The actual count of virus-fighters.

The actual count of the cleanup crew.

The actual count of allergy responders.

The actual count of basophils.

Your blood sugar at the moment of the draw; the first look at metabolic health.

A waste product your kidneys clear; part one of the kidney check.

A muscle byproduct your kidneys filter; part two of the kidney check.

The two kidney markers compared; helps separate dehydration from true kidney strain.

Your body's main electrolyte; fluid balance, blood pressure, and nerve function.

The electrolyte your heart rhythm depends on.

Works with sodium to keep fluids and pH in balance.

Reflects your blood's acid-base balance; kidneys and lungs working together.

Bones, muscle contraction, and nerve signaling in one number.

All the protein circulating in your blood; nutrition and liver function at a glance.

The liver's main protein product; low can mean liver or nutrition issues.

The immune and transport proteins; the other half of your blood protein.

The balance between the two; shifts can flag liver or immune conditions.

What's left when old red cells break down; the liver clears it, so it's a liver check.

An enzyme from liver and bone; elevated points to one or the other.

The most liver-specific enzyme; the primary marker for liver stress.

An enzyme from liver and muscle; read alongside ALT to tell them apart.

Your kidneys' estimated filtering power; the single best kidney function number.

Your average blood sugar over the last three months; the number that defines prediabetes and diabetes.

Essential for energy, nerves, and red cell production; low B12 mimics low-T symptoms like fatigue and brain fog.

B12's partner in red cell production and DNA repair; low folate drains energy the same way.

The hormone-like vitamin tied to testosterone production, mood, immunity, and bone strength; most men run low.

The fat circulating in your blood; diet and metabolic health show up here first.

The headline number; context for the breakdown below.

The "good" cholesterol that clears arteries; exercise and hormones move it.

Total against good; a sharper heart-risk signal than either alone.

The "bad" cholesterol that builds plaque; the main lipid target.

The master thyroid signal; an underactive thyroid causes fatigue, weight gain, and low mood that get blamed on testosterone.

The prostate health marker; a required baseline before testosterone therapy and monitored throughout.

The pituitary signal for sperm production; tells us whether a testosterone problem starts in the brain or the testes.

The pituitary signal that tells your testes to make testosterone; the other half of that answer.

Your primary estrogen; men need the right amount, and testosterone therapy can push it up.

All the testosterone in your blood, bound and free; the headline number.

The protein that locks testosterone up; explains why "normal" total T can still feel low.

The testosterone actually available to your tissues; the number that tracks how you feel.

The downstream marker of growth hormone; recovery, muscle maintenance, and aging.
