COC Essential Blood Tests is designed to give you a clear, clinically grounded snapshot of how key systems are functioning right now. It brings together a full blood count with liver and kidney function markers so you can move from “I feel a bit off” to objective data you can interpret and act on.

The full blood count looks at the make-up of your blood, including red cells, haemoglobin and haematocrit, alongside platelets and the main white cell types. This helps build a picture of oxygen-carrying capacity, inflammation and immune activity. It can add context to symptoms such as ongoing tiredness, reduced exercise tolerance, frequent minor infections, or recovery that feels slower than usual. It can also be useful as a baseline if you are monitoring how you respond to changes in training, stress, sleep, or diet over time.

Liver function markers, including enzymes such as ALT, ALP and GGT, as well as proteins like albumin and total protein, provide insight into liver health and how your body is processing and producing key compounds. This can be relevant if you are trying to make sense of abnormal results, reviewing alcohol intake, considering the impact of certain medications, or looking for reassurance that things are within expected ranges.

Kidney function markers, such as creatinine and estimated glomerular filtration rate (eGFR), alongside electrolytes like sodium and potassium, help assess filtration and fluid balance. These results can inform conversations about hydration, blood pressure risk, medication safety, and overall metabolic stability.

Taken together, this panel offers a practical baseline across core systems. It does not diagnose a specific condition on its own, but it can highlight patterns worth addressing, support informed next steps with a clinician, and give you a reference point for future testing.
