Why bloodwork is the scoreboard
You cannot feel your hematocrit, your lipids, or your liver enzymes. Bloodwork is the only objective readout of how your body is responding, and a trend across several draws says far more than any single number. The goal here is logistics: knowing what to measure, when to measure it, and how to keep a clean record — not interpreting results, which is a conversation for you and a clinician.
The panels worth running
A broad baseline usually pulls from a handful of panels. Add markers specific to what you are running:
- →Hormones — total & free testosterone, estradiol (E2), SHBG, LH/FSH, prolactin.
- →Complete blood count — hematocrit and hemoglobin matter most here.
- →Lipids — total cholesterol, LDL, HDL, triglycerides.
- →Metabolic — liver enzymes (ALT/AST), kidney markers (creatinine/eGFR), fasting glucose or A1c.
Baseline first, then follow-ups
A draw before you start anything is the most valuable one you will ever take — it is the reference every later result is compared against. After that, follow-up draws are usually spaced to catch changes as they develop rather than after the fact. Logging the date of each draw is what turns isolated numbers into a trend line.
Timing the draw
When you draw matters. For injectables, a trough draw (right before your next dose) gives a consistent, comparable low point; a peak draw shows the high end. Pick one convention and stick to it so your numbers are apples-to-apples over time. Many panels are also drawn fasted in the morning — note the conditions of each draw so a swing is real signal, not just a different time of day.
Reading a value against its range
Every result comes with a reference range printed on the report, and that range is the one that matters — it reflects your lab’s specific assay. The tracker flags values outside a common range as a visual cue only. A flag is a prompt to pay attention and discuss, not a diagnosis, and a single out-of-range value is far less meaningful than a direction of travel across draws.
Building the habit
The people who get the most from bloodwork are simply the ones who do it on a schedule and write everything down. Enter each draw the day you get it, keep the units consistent, and let the trend accumulate. Over a few cycles you will have something most people never build: a personal baseline you can actually reason from.
