The patient portal changed everything, and not entirely for the better. Results now arrive on your phone at nine at night, four days before your appointment, as a wall of forty-odd rows with little flags on them. I have watched friends spend an entire weekend frightened by a number that turned out to be meaningless, and I have watched one ignore a real one because it was buried between two harmless ones.
At my physical two years ago I brought the printout in with half of it highlighted. My doctor took the pen out of my hand, circled five lines, and said: read these, ask me about these, and stop reading the rest. It was the most useful five minutes of that decade.
I am a retired nurse, not your clinician. These are the five I was told to watch and the questions I ask about them — every one of these is a conversation for your own doctor, who has your history in front of her.
The first line she circled, and the one that surprised me most.
Hemoglobin is the one everyone knows and the one that shows up "normal" for years. Ferritin is the stored iron underneath it, and it can run down long before the hemoglobin moves. They are not the same thing and only one of them was ever low on mine.
The question worth asking: was ferritin actually run, or only hemoglobin? On a standard panel it is often not included unless someone asks for it.
Thyroid, and the reason it is on the list is not the number itself — it is that the reference range printed beside it is wide, and the bottom of the range and the top of the range are two quite different experiences of being alive.
Ask what your number was five years ago. A value that has moved steadily inside the normal range is a different conversation from one that has sat still. Trends are the whole point of these sheets and the portal presents everything as a snapshot.
This is the third line and it is the one that accounts for the two years I spent assuming I was simply getting older.
I was tired in a way I could not describe to anyone. Not sleepy — heavy. I put it down to sixty-five, to winter, to being a widow's age. It had been low on two successive panels and nobody had circled it, including me, because it sits near the bottom of the page and does not come with a red flag.
In Minnesota, from October to April, there is essentially no useful sun for this. My doctor was blunt about it: at this latitude, at our age, she expects it to be low unless something is being done about it.
I want to be careful here. I am not telling you that a supplement will fix your tiredness — mine improved and I cannot prove the two are connected, and "correlation is not causation" was drilled into me for three decades. What I am telling you is that it is worth being on the list of five things you actually look at, rather than the thirty-five you scroll past.
Fourth. This is the three-month average of your blood sugar rather than a single morning's reading, which is why it is more useful than the fasting glucose sitting next to it.
The reason it belongs on a five-item list for women our age is that the range between "fine" and "we should talk" is where a great many of us quietly live for a decade, and it moves slowly enough that no single year's result looks alarming.
Ask for the last three values, not this one. Written next to each other they tell a story that no single number does.
Fifth, and the one most people have never heard of.
It is an estimate of how well the kidneys are filtering. It matters after sixty mainly because it governs what else is safe — the dose of common blood pressure medications, some diabetes drugs, and the ordinary over-the-counter anti-inflammatories that women our age take for knees and backs without thinking of them as drugs at all.
The question: given this number, is everything I am taking still at the right dose — including the ibuprofen I buy myself? That last part is the one that does not come up unless you raise it.
She was not being dismissive when she said to stop reading the rest. Her argument was that a panel has forty rows and a handful of them will be flagged high or low on any given day in any healthy person, and the anxiety those flags generate has a real cost — appointments made in a panic, sleepless weekends, and worse, the habit of tuning the whole sheet out because it always looks alarming.
Five lines you actually read beats forty you skim and one you avoid.
I keep a single sheet of paper in the same kitchen drawer as the fuse box list. Five rows down the side, one column per year. When results land I write in five numbers, which takes two minutes, and then I close the portal.
What that gives me at the appointment is the thing the portal cannot: five short rows of history, in order, that I can put on the desk. My doctor has twice now looked at that page and changed what she was going to say. That is worth far more than my having read all forty rows on a Friday night.
This part is as useful as the five, and I have never seen it written down anywhere, so I asked her to explain each one and wrote it on the back of the printout in the parking lot.
The white cell count that is slightly high. Mine was flagged three years running and I lost a weekend to it the first time. A single mildly elevated white count in a woman who feels well is, more often than not, a cold you had eleven days ago, a bad night's sleep, or the fact that you were anxious in the chair. It is a number that moves for ordinary reasons. What matters is a trend across several draws, and one flagged result is not a trend.
Total cholesterol on its own. The single total number is the one that gets read aloud at kitchen tables and it is close to meaningless by itself. It is a sum. Two women with the same total can be in completely different situations depending on what it is made of, and after sixty the picture also involves your blood pressure, whether you smoked, and your family history. If you are going to look at the lipid rows at all, the useful conversation is about the whole panel with someone who knows your history — not about whether the total went from 204 to 211.
The liver enzymes that are one point over. These sit right in the middle of the page with a flag on them and they frighten people badly. They also move with a glass of wine, a new statin, a course of antibiotics, or paracetamol taken for a bad week of knees. My doctor's rule for herself: one point over on one draw is a "check it next time," not a "call me."
I am repeating her reasoning rather than making a clinical claim of my own. The point is not that these three never matter — it is that they are the three most likely to consume your weekend for no reason, and knowing that in advance is worth as much as knowing which five to read.
Thirty-one years on the other side of that desk taught me that the quality of the answer depends almost entirely on the shape of the question. "Is my blood work okay?" gets you "everything looks fine," because that is the honest summary of thirty-eight normal rows, and it closes the subject.
What I ask instead, in this order, from my sheet of five:
"Was ferritin run this time, or only hemoglobin?" — a yes-or-no question that cannot be absorbed into a general reassurance.
"What was this number five years ago?" — the single most productive question I have found. It moves the conversation from snapshot to trend, and the computer can answer it in four seconds.
"Given the kidney number, is everything I take still at the right dose, including what I buy myself?" — the over-the-counter part is the half that does not otherwise come up. Nobody thinks of the ibuprofen in their handbag as a drug with a dose.
"Which one of these would you watch if you were me?" — asked last, after she has seen the sheet. Twice now the answer has been a line I would not have picked.
I want to be straight about my own record here, because I was a nurse and it did not save me from any of this.
I read the portal at night. Every time. Results would land around nine and I would open them in bed on a small screen, and a flagged row at nine at night is a different object than the same row at ten in the morning. I did that for two years before I made the rule I now keep: I do not open results after six in the evening, and I do not open them at all in the four days before an appointment where someone is going to explain them to me.
I also highlighted everything, which is the same as highlighting nothing. The sheet I brought to that physical had twenty-two rows marked and she circled five of them, and the reason the five stuck is that everything else came off the page.
And I ignored the vitamin D line on two consecutive panels — not because I did not understand it, but because it sat low on the page under things that looked more serious, and I was tired, which is the exact circular joke of that particular number.
She kept the paperwork — that is why it held up.
Are your own documents where someone could find them?
