Brief Answer:
Please upload all reports and consider for peripheral blood smear test

Detailed Answer:
Hello
I had gone through your question very diligently and I appreciate your concern
Low MCV and low MCH means volume of the RBCs are less and hemoglobin concentration in each RBC is less but you need not to worry your hemoglobin is good 13gm/dl.
It could be physiological which means normal
Here I would like further information for better assessment of the condition.
1. Other than tiredness what all symptoms are you having
2. If possible upload me the whole reports

I would advise you for a test called as peripheral blood smear to study RBCs morphology, cell type or any abnormal cells.

Please write back to me so that I will be able to tell you more accurately

Hello
welcome again and thanks for follow up question
Since I can't physical examine you to get more clues So I would advise you to visit a gynaecologist for physical examination and an ultrasound to rule out pregnancy or retained product of miscarriage.

At first you can do urine pregnancy test which can be done at home to rule out pregnancy.
Meanwhile take rest and just relax.

Hope this answers your question

Brief Answer:
Please consider these guidelines

Detailed Answer:
Hello
welcome again and thanks for the reports
Looking at your detailed description and lab reports I would advise you to follow these guidelines
You should take urine pregnancy card test which can be done at home if you had unprotected sex after the miscarriage.
you should take pantoprazole or ranitidine group of drugs with antacids for 2 to 3 days
Just relax and remain cheerful
your all the blood reports are within normal range so you need not to worry
You can take multivitamin and minerals supplements
Have lots of fresh fruits and vegetables
Avoid fatty fried spicy and junk food
since you had a miscarriage and you are not having periods since 8 weeks after that which warrants detail evaluation to find out underlying cause by hormonal studies, ultrasound and further investigations.

Hope this answers your question
Please feel free to discuss further I will be happy to help you

Detailed Answer:
Hello
Welcome again you need nor to worry
Your MCV and MCH findings are not too low, it's just near lower margin of normal range.
so you just relax it varies with various laboratory since your hemoglobin report is ok, if you still want to further investigate than you can go for test to see the morphology or abnormal cells in the blood and that test is known as peripheral blood smear.

You didn't get period that is a matter of concern, you should consult a gynaecologist for physical examination and investigations as I advised you in previous reply to find out the underlying cause and treatment for withdrawl bleeding.

Hope this answers your question
Please feel free to ask of you still have any more doubts.

Hi, I have been experiencing swelling on my left shoulder (in the neck region) and there s what appears to be a swollen gland in my left neck. The headache is mostly on the right side of my head and breathing is sometimes correlated with irregular heartbeats. I am on HBP medications, but the docs have done tests (ultra sound, EGC, xrays, biopsy) for thyroid, but all are negative. What could these symptoms be and what are the possible treatments?

My husband is 3 months post op Thyroid Cancer. Thyroid was removed as well as 6 metastatic nodes. 148 mc Radioactive Iodine was given & I131 scan showed only residual tissue. He currently takes his synthroid 150 mg. But it has been ineffective. 6 weeks ago he had an onset of pain in tailbone. Which has progressed to severe pain & inability to stand or walk correctly. Along with this his RBC Hemocrit & Hemoglobin levels are low, but his Platelet function times are elevated. He has had several CBC W/DIFF labs. His PFT has been up to 206- 247 ranges & his PFT EPI up to 179. They are consistently high with the exception of 2 different times being normal out of 6 draws. His ENT just removed tonsils with bleeding complications. He believes something is wrong & is sending him to Hematology at Vanderbilt. My question is could the bone pain be related to his levels? Lukemia? Or is that not usual or is it two separate issues such as a blood disorder and possibly a discount issue?

Hello, I am trying to figure out why I ve been getting rashes on and off for the past couple of years whenever I go on vacation and get exposure to the sun and ocean. I have Addison s Disease and hypothyroidism and don t know if the bumpy clustery bilateral rash has to do with my autoimmune disorders. The rash goes away in a few days and is non-itchy but uncomfortable. It usually starts on the tops of my feet and spreads to my hands (in between fingers too)...right now it is on my thighs and hips.
