Anaemia should be understood before an elective platelet-rich plasma injection. A low haemoglobin result is not simply a number to work around so a treatment can proceed. Its cause, severity, symptoms and trend matter, alongside the amount of blood to be taken and the reason for PRP.
There is no single evidence-based haemoglobin threshold that this article can use to clear everyone for treatment. A careful clinician should investigate a significant blood-count abnormality, decide whether the injection should wait and explain what needs to happen first. The aim is safer care, not a more complicated package of tests.
Can you have PRP with anaemia?
Haemoglobin is carried in red blood cells and helps transport oxygen. Platelets are a different part of the blood. PRP preparation aims to concentrate platelets, but it still begins with taking a blood sample from you. A satisfactory platelet count does not cancel out anaemia, and a low haemoglobin result does not explain whether the platelets function normally. [1]
The 2025 GRIIP musculoskeletal PRP consensus states that a significant abnormality in the full blood count should be investigated before PRP. That is more useful than treating any isolated laboratory threshold as a universal permission slip. The recommendation is based largely on expert opinion, not trials that establish a safe haemoglobin level for every injection protocol. [1]
Ask The London PRP Clinic, part of The Wellness, about a pre-treatment review if you have been told you are anaemic or have an unexplained abnormal blood count. Send the original laboratory report before arranging a procedure.
Is anaemia always caused by low iron?
No. Iron deficiency is one cause, but anaemia can also be related to inflammation, vitamin deficiencies, kidney disease, blood loss or other conditions. The pattern of the full blood count and the medical history guide further investigation. Taking iron without understanding the cause can delay the right assessment. [2]
For confirmed iron deficiency, the British Society of Gastroenterology guideline emphasises finding the cause as well as replacing iron. In adults, particularly where there is no obvious explanation, gastrointestinal assessment may be important. The appropriate pathway depends on age, sex, symptoms and other circumstances, not on a PRP clinic's desire to proceed with treatment. [2]
If you already take iron, tell the reviewing clinician the preparation, dose and duration. A result that has not improved needs review rather than simply adding more supplements.
What should be checked before deciding to proceed?
The clinician should consider the haemoglobin level and trend, symptoms, likely cause, relevant medical conditions and medicines. Other blood-count abnormalities may change the assessment. A treatment involving repeated blood draws may need a different discussion from a single procedure.
Useful records include the full blood count, ferritin and any other investigations already arranged by your GP or specialist. Do not assume that every patient needs the same panel. The right test is the one that resolves an uncertainty affecting the decision.
A person with a longstanding, explained and stable mild abnormality is not the same as someone with a new falling haemoglobin and no diagnosis. Both deserve an individual assessment; neither should be cleared by an online checklist.
Will correcting iron deficiency make PRP work better?
That is not established by the sources cited here. Treating a deficiency may be appropriate for your general health, but it does not prove that a particular joint or tendon injection will be more effective. Safety assessment and treatment effectiveness are separate questions.
Similarly, evidence about blood-count assessment before musculoskeletal PRP should not be presented as proof that scalp PRP will reverse hair loss caused by iron deficiency. Hair loss needs its own diagnosis. Paying for an injection before investigating a reversible cause can leave the central problem untreated.
Should you postpone your appointment?
Tell the clinic before the day of treatment. Postponement may be appropriate while an unexplained or significant abnormality is investigated, particularly if you are symptomatic or the result is worsening. The clinician should explain the reason and what evidence would support reconsidering treatment. [1]
Do not stop anticoagulants, antiplatelet medicines or other prescribed treatment yourself. These medicines create separate bleeding and cardiovascular questions, and any changes need the relevant prescriber's advice. An elective procedure does not justify an unsafe medication interruption.
Contact the clinic with your results and medicine list. Ask whether you need a consultation first and confirm the fee and cancellation terms before booking a procedure that may need to wait.
What makes a good pre-treatment plan?
A clear plan should state the explanation being investigated, who owns that investigation and whether PRP is deferred. It should also set out the alternative care for your joint or tendon problem while the blood result is addressed. Exercise-based rehabilitation or another treatment may still be appropriate, depending on the diagnosis.
For busy people dividing care between private clinics and their usual GP, a short written summary is valuable. It prevents the same blood tests being repeated while nobody takes responsibility for the cause. Ask for copies of the findings and recommendations to share with your responsible clinician.
Which symptoms need urgent assessment?
Chest pain, severe breathlessness, collapse or marked acute weakness require urgent medical assessment. Black stools, vomiting blood, substantial bleeding or rapidly worsening symptoms should not wait for an elective injection consultation. If a laboratory or clinician has told you a result is urgent, follow that advice rather than using an article to judge it yourself.
Questions patients often ask
Can I have PRP if my platelet count is normal? A normal platelet count does not settle anaemia, medicines or the underlying diagnosis. It is only part of the safety assessment.
Is there a minimum ferritin for PRP? The cited evidence does not establish a universal ferritin target for treatment success. Avoid arbitrary "optimal" numbers presented as guarantees.
Should I buy a course while I correct my iron? Establish suitability first. Ask how the clinic handles deferral and whether any payment is refundable before making a commitment.
Does donating blood recently matter? Mention it, together with any symptoms and recent results. The clinician can assess the total picture rather than applying a generic interval.
Discuss your suitability before committing to PRP. A decision to investigate or wait can be the most useful outcome of a careful consultation.
