What I look for when I read a lab folder for the first time

Yvette Rose · 7 min read

When a new client sends me her bloodwork, it usually arrives as six PDFs from three different portals across four years. Each one was read by someone, once, on the day it came back. Nobody has ever laid them side by side. That is the first thing I do, and it is the most useful thing I do. A single result tells you where you are. Four years of results tell you which way you are moving, and direction is what matters in your forties. I am going to walk you through the order I read in, what I am looking for on each page, and what I do when I find it. I do not diagnose. I read, I ask, and I send you back to your doctor with better questions.

First, I read the dates and the gaps

Before any number, I look at what was tested and what was never tested. A folder with four cholesterol panels and no ferritin tells me something about the doctor. A folder with TSH every year and never a free T4 tells me the thyroid has been screened and never examined. A folder with fasting glucose but no fasting insulin tells me that a decade of early metabolic change could have gone unmeasured. The absences are as informative as the flags. I write them down first, because they become the list you take to your next appointment.

Then I check the conditions. Were you fasting? Was it the same lab each time, since reference ranges differ between labs? Were you sick that week? Were you on an iron supplement, a statin, thyroid medication, or a hormone? Any of those change how a number should be read.

Second, I read the direction a number is moving

A number inside the range that has moved. A lab flags a result when it crosses the printed line. It does not flag a result that has travelled from the bottom of the range to the top over three years. An ALT that went from 14 to 31 has more than doubled and will show no asterisk on most reports, because the lab's upper limit might be 40 or 50. The American College of Gastroenterology recommends an upper limit closer to 25 for women. A ferritin that went from 60 to 18 is a woman losing iron faster than she is replacing it, and at 18 most labs still call it normal.

A number that moved with no change in life. Cholesterol that rose while your diet stayed the same. Weight that rose while your food stayed the same. Both are far more likely to be hormones and muscle than willpower, and I say so, because most women arrive assuming it was their fault.

Two numbers moving together. Rising ALT next to rising fasting insulin next to rising triglycerides is one pattern. Falling ferritin next to heavier periods next to a lower hemoglobin is another. Raised TSH next to raised cholesterol next to constipation and cold hands is a third. I am looking for company. A flag with company is a story.

Third, I go through the pages in this order

Iron. Ferritin, and ideally iron, transferrin saturation, and a full blood count. Ferritin is the store. In a menstruating woman in her forties, I want to see it comfortably above 30, and higher if her hair is thinning or she is exhausted. The reference range on many reports starts at 15 or even 11. I read it next to hs-CRP, because inflammation pushes ferritin up and can hide a real deficiency.

Thyroid. TSH, free T4, free T3, and thyroid antibodies. TSH alone is the pituitary's opinion of the thyroid. It is a useful screen and a poor examination. Antibodies matter because autoimmune thyroid disease is common in women in this decade and can be present for years before TSH moves.

Blood sugar and insulin. Fasting glucose, fasting insulin, and HbA1c. Glucose stays normal for a long time because insulin is working overtime to keep it there. The insulin number is where the early story lives. If fasting insulin has never been run, that goes on the list.

Liver. ALT, AST, and GGT. I read them against the tighter limits, I read them against alcohol, and I read them against the insulin and triglyceride numbers, because fat in the liver in this decade is far more often metabolic than it is the wine.

Lipids. Total cholesterol, LDL, HDL, triglycerides, and if the doctor will run it, ApoB and lipoprotein(a). The ratio of triglycerides to HDL tells me something about insulin resistance. Lipoprotein(a) is inherited and is worth testing once in a lifetime, especially if a parent had early heart disease.

Inflammation. hs-CRP. This is the number that tells me whether every other number is sitting in a calm body or an inflamed one. It changes how I read the iron, the lipids, and the liver.

Vitamin D and B12. Both are commonly low, both affect energy and mood, and both are cheap to correct once you know.

Hormones, with care. In perimenopause, estradiol and FSH on a single day tell you almost nothing, because they change week to week. I do not use a single hormone reading to make a case. I use symptoms, cycle history, and the metabolic pattern above. A menopause trained doctor does the same.

The folder is one body. It deserves one reader.

Fourth, I ask about your mother

Before I ask what you eat, I ask what your mother's forties looked like. When did her periods stop. Did she have thyroid disease, early heart disease, diabetes, heavy bleeding, fibroids, a hysterectomy. What you inherited is biology and shows up in the folder. What you were raised in is pattern and shows up in how you eat, sleep, and cope. They are two different problems and they need two different answers. The folder often carries both, and I want to know which is which before I say a word about breakfast.

What I would do first

Get every result into one document. Print them or put them in one spreadsheet, oldest to newest, one row per test. Do this before you see anyone. It is the single most powerful thing a woman can do for her own care and it takes an evening.

Ask for the missing tests by name. Ferritin, hs-CRP, fasting insulin, free T4, free T3, thyroid antibodies, vitamin D, B12. Your doctor may not order all of them, and they may not all be covered, and that is a conversation worth having in the open.

Fix the boring things while you wait. Sleep, protein at breakfast, a walk after dinner, alcohol paused for six weeks. These move ALT, insulin, hs-CRP and triglycerides in the same direction and they give the next panel something to compare against.

Bring the trend. When you sit down with your doctor, show them the three year line rather than the latest page. A doctor who sees 14, 22, 31 on one page reacts differently to a doctor who sees 31 with a reference range of 7 to 45.

Know who reads what. I read the folder and the life around it. Your doctor orders, diagnoses, and treats. A menopause trained doctor handles hormone therapy, which is the most effective treatment for hot flashes and night sweats. A dietitian handles medical nutrition. If I think you need any of them, I say so and I help you find them.

Caveats. If you are pregnant, on thyroid medication, on blood thinners, on diabetes medication, or have a history of disordered eating, changes to food, fasting, or supplements go through your prescriber first, every time.

When to push harder with your doctor

Push if you have asked for fasting insulin, ferritin, or a full thyroid panel and been told they are unnecessary without an explanation. Push if a number has doubled inside the reference range and nobody has commented. Push if three or more results are drifting in the same direction and the plan is to recheck in a year. Push if you are told your symptoms are stress or age and no one has looked at iron, thyroid, or insulin. Ask the question I use most: what would we expect to see on this panel if my symptoms were being caused by something we can measure. A good doctor will answer it. If the answer is a shrug, ask for a referral, or find a doctor who works with women in this decade every day.

If you want to do this work yourself with structure, the 10 Day Reset workbook lays it out page by page, with the questions to bring to each appointment.

Questions I get asked

What blood tests should a woman in her forties ask for?

A full blood count, ferritin, hs-CRP, fasting glucose with fasting insulin and HbA1c, ALT, AST and GGT, a full lipid panel, TSH with free T4, free T3 and thyroid antibodies, vitamin D, and B12. Lipoprotein(a) is worth testing once. Your doctor decides what is appropriate for you, and some may not be covered, so ask in the open.

Why do you read the trend instead of the reference range?

A reference range is the middle 95 percent of a population, and it flags a result only when it crosses a line. It does not notice a value that has doubled while staying inside the line. In your forties, direction over three or four years tells you far more than a single day's number.

Can a health coach read my bloodwork?

I read the folder for patterns and I help you ask better questions. I do not diagnose, order tests, or treat, and I refer you to a doctor whenever something needs one. Diagnosis stays with your doctor. Understanding your own results is yours to keep.

Why do you ask about my mother before my diet?

What you inherited is biology and it shows up in your labs: thyroid disease, early heart disease, when her periods stopped. What you were raised in is a pattern and it shows up in habits. They are two different problems with two different solutions, and I want to know which one we are looking at before I suggest anything.

Should I test my hormones to confirm perimenopause?

A single estradiol or FSH reading in perimenopause changes week to week and rarely settles anything. Perimenopause is usually recognized by age, cycle changes, and symptoms. A menopause trained doctor will tell you the same, and can discuss hormone therapy if hot flashes or night sweats are affecting your life.
