Hemoglobin at high end of normal

36F 168lbs. Severe health anxiety and GAD. I had my annual physical and blood work done today and my hemoglobin came back at 15.4 g/dL, Hematocrit 44.3%, RBC 4.81 M/uL, MCV 92 fL. I am curious if this would be a concern of any sort?

Vitamin D deficiency

34M, 90+kg. Just got my vitamin D blood test done.

For the past months, I’ve experienced intense fatigue, malaise, headaches, nausea, muscle tingling or neuropathy etc. Full blood count came back normal except low neut. Two visits to the haematologist and multiple GP visits none have been able to pinpoint what’s wrong with me. I’ve heard vitamin deficiency could cause my symptoms but I’m keen to investigate if this low levels could be driven by something more serious.

I have to admit that I spend less time in the sun. I leave for work at dawn, work in the office and return home at dusk. Maybe this is it or something more serious going on with me.

Elevated Kappa/FLC Ratio

Trying to make this as short as possible. My kappa and FLC ratio have been elevated for three years now. I have requested repeat electrophoresis and the only thing that keeps flagging high is IgG. last year it mentioned no M spike. This year the report said, "Cannot exclude a monoclonal peak in the gamma region. Please correlate with immunotyping" The immunofixation serum mentioned, "No definitive monoclonal protein detected"

I have suspicions of MGUS or wondering if its possible polyclonal, or is this just nothing? My hematologist dropped me from her practice and said she doesn't need to see me anymore.

I do my own studying so if anyone can point me in the right direction, I would greatly appreciate it.

B12 elevation without supplementd

Hi everyone,

I’m a bit anxious (Health anxiety) about some blood test results and symptoms and would appreciate some perspective.
My recent lab work showed a vitamin B12 level of **904 pg/mL**, with the reference range being up to **771 pg/mL**. I am **not taking any B12 supplements or multivitamins, no Energy Drinks.**

Everything else in my blood work came back normal:
Complete blood count (CBC) normal
Liver enzymes (GOT/AST, GPT/ALT, GGT) normal
Kidney function (creatinine) normal
So far, no other abnormalities were found.

The reason I started looking into this is that I’ve been experiencing **occasional night sweats** since around January. It’s not every night – maybe 2–3 times per week at most, sometimes less. It’s also not severe; I never wake up completely drenched or need to change clothes or bedding. It’s mostly mild sweating around the chest area in Front and sometimes at the hairline.
I don’t have any other major symptoms like fever, weight loss, or persistent fatigue.
However, I read some studies mentioning that elevated B12 levels can sometimes be associated with conditions like liver disease or even different types of cancer (like stomach, colon, pancreas, etc.), which made me quite worried. I understand those studies often mention correlation rather than causation, but I’m still unsure how to interpret this in my case.

My question is basically:
Can a mildly elevated B12 level like this happen without any serious underlying condition?
Could the night sweats be unrelated and benign given the mild and inconsistent nature?
Would this typically warrant further investigation, or is observation and repeat testing enough?

Thanks a lot in advance to anyone who takes the time to read and respond.

High Iron??

I got this curveball in my bloodwork. My doctor suspected I might have low iron lol. I’ve never heard of anyone having high iron, & ferritin is normal so I don’t really understand. Plus, I have hEDS & POTS so I was more expecting either normal labs or low iron/ferritin. Does anyone have any insight?

Diffused Splenic Granulomas

I am a 38yo female. I've been having health problems non stop for 10 years. Ive had surgeries on my spine, hands and stomac, chronic pain or feeling bad to worse, I have c-ptsd from people not believing me when I'm in pain. There have been many many problems that I won't bore yall with but one. I had my ovaries and uterus removed due to endometriosis and adenomyosis at 27. I've gotten excited over tests in the past, hoping they finally showed something so I could be diagnosed and treated. I had a ct scan the Friday before last and it showed diffused splenic granulomas. They called me on a SATURDAY and made an appointment for Monday. I got a call THAT day from Haema-Oncology and now I'm losing my mind. My appointment is 5 days from now. They've only ever pushed me through that fast in scheduling when it's been awful news.

Everything I usually do to calm myself is not working. Does anyone know anything about them? Are they often non sequitur? Anything I should ask this noctor?

why did my hemoglobin and hematocrit drop so much after only one week?

hello all,

i am very new to all things iron deficiency and blood issue related after finding out recently that my ferritin is at 7ng/mL and i posted about my situation yesterday in r/anemic but wanted to pose a question to this sub as well. my hemoglobin, hematocrit and red blood cells were all high at my initial cbc, despite my low iron and ferritin, which is why a hematologist i saw one week later diagnosed me with iron deficiency and secondary polycythemia. i have a follow up with her next week and we are still waiting on some gene tests results, but at that appt she ordered another cbc and my hgb and hct dropped quite a lot with only a week apart from the first test. i assumed it was bc i may have been more dehydrated in the first test, but now google is saying that a drop that much is something else. i have pictures here of both tests. i was feeling so bad this morning i almost went to the ER as my symptoms have been worsening and my heart rate has been very elevated and got up to 141 earlier today, but i am very active at my job which makes it worse. i’m feeling better now and trying to tough it out until my follow up appt. anyone have any ideas?

Why don’t doctors care about this? It’s been declining for a few months.

No prescribed iron, no further looking into, just nothing. Frustrating .

B12 deficiency Haematology uk

Has anyone seen or can recommend a haematologist in the uk that understands b12 deficiency or functional b12 deficiency. My GP says his hands are tied.

He referred me to haematology who said he didn’t a good understanding of a b12 deficiency and to ask my Gp to find some that has a special interest.

GP says he doesn’t have time, yet if I find someone he will refer me. I feel I’ve got more chance of finding a golden unicorn.

If anyone has any suggestions I would be extremely grateful.
Many thanks x
